T RACE’s range of linear bearings are setting new standards due to their innovative design and technical concepts. The family MONORACE, based on different C-shaped rails with a wide range of sliders, is offering unique linear solutions for all kinds of automation applications for many industries. T RACE’s system with roller sliders and internal raceways, offer the markets highest performing system, along with being size wise the most compact system.
HIGH PERFORMANCE The new rails MRG series rails are the evolution of the consolidated MR series. The new rails have a number of improvements related to the contact geometries, new materials for increased strength and depth of hardening - T RACE-NOX 2.0 last generation hardening treatments, showing our commitment to continuous technological improvement of T RACE products. The new MRG43 is companied with a new version MRG46 with increased thicknesses of the flanges to achieve a more rigid rail for critical application, where the rail becomes a self-supporting part of the structure. The MRG and MR rails allow combinations of different sliders to obtain self-aligning systems based on pairs of rails. Such self-aligning system is able to compensate for surface assembly inaccuracies on longitudinal and transverse plane, like non precise carpentry, aluminum structures or bent sheet metal structures, hereby avoiding costly processing / machining to achieve precise parallel rail installation. The internal raceways with protected roller wheels, along with lateral seals and strong wipers, incorporating preoiled felts makes the MONORACE linear system very suitable for even harsh ambients, dust, humidity etc. The rollers of large diameter are rarely sensitive to impurities entering the linear system. STANDARD The ML series rail represents a simplified version of the MR series with similar dimensions. The thinner C shaped rails have the concave inner raceways in which slide rollers of single row bearing with shields and inner ball cage made in metal. The carriages in various versions are equipped with wipers with lubricating felt. The ML series does not provide self-aligning features COST EFFECTIVE LAN rails are made from sheet steel and shaped by high precision, ultra-smooth forming rollers. They are then case hardened using our revolutionary TRACE-NOX nitriding and black oxidising process to ensure an extended lifetime and excellent corrosion resistance. The slider bodies are cataphoretically blackened for maximum corrosion resistance. The rollers are made from core tempered and precision ground, bearing grade steel. The ball bearings are lubricated for life with wide temperature range bearing grease and protected by 2Z rated metal shields. Robust elastomer raceway wipers are fitted at both ends of the slider to protect the rollers and keep the raceways clean. The wipers incorporate oil-impregnated felt pads to keep the points of contact between raceway and roller properly lubricated, for the lifetime of the rail. Wipers are held in place by a simple clip and can be removed and replaced easily. INOX LAX series rails and PAX series sliders are constructed entirely of stainless steel and are a simple and functional solution for applications that require high corrosion resistance,. The rails and sliders bodies are made from 300 Series stainless with rollers made from 440C. These are particularly suitable for food processing, pharmaceutical, and medical applications or in difficult environments such as marine environments where there is exposure to highly corrosive agents. The slider is equipped with 3 rollers. The middle roller is eccentric and is used to adjust the slider preload. The sliders are easily washable for applications subject to frequent cleaning and do not release particles into the environment and are particularly suitable for clean rooms. They are available in two sections: 26 and 40 mm.
The roller linear MODULAR system FLEXRACE offers the maximum flexibility configuration due to the original shape of the guide FXRG, basic component of the system, shaped with 3 raceways arranged at 90 ° to each other on which can slide the rollers R..G 43 series indifferently on each of the three raceways. The using of the single guide or two or more parallel guides gives rise to a number of combinations capable of satisfying each specific need for linear motion and offering exceptional ability to self-alignment. Like the MONORACE’s MR & ML rails, FXRG rail is constructed in high strength steel hardened with the last generation T RACE NOX 2.0 hardening treatments, for a further improvement of the performance and durability.
The ball cage linear slide HIGH LOAD of SF series offers a very high load capacity in a compact size. They are built from the base of the rail ML series with one or more sliders that move through the interposition of one or more robust ball cages with large diameter balls. Like the MONORACE rails are made by the same production process and hardened with thermochemical process patented T RACE NOX 1.0. They are suitable for horizontal movements with high loads in all directions and for movements where the stroke available is completely used.
GENERAL CHARACTERISTICS
The rails of MRG, MR and ML series are high precision cold drawn profiles, made from steel alloy that with our patented T RACE NOX thermo-chemical hardening process provide a very hard surface for high wear resistance, along with and at the same time a good protection against corrosion, even in critical environments.

TECHNICAL FEATURES
ROLLER POSITIONING Sliders are available with either 3 or 5 rollers. For the 3 roller version, the first and third roller are fixed concentric rollers that run on the same raceway. The second roller is eccentric and runs on the opposite raceway. The eccentric feature is used to adjust the slider preload in the rail. For the 5 roller version, the two lateral and the central roller are fixed, and run on the same raceway. The second and fourth roller are eccentric and run on the opposite raceway. The eccentric feature is used to adjust the slider preload in the rail. Because one raceway contacts more rollers than the other raceway, the sliders have a preferred loading direction. The slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading. Care during assembly is required to ensure the maximum load capacity of the system is achieved.
3-ROLLER SLIDER
5-ROLLER SLIDER 14
RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the rail’s raceways.
The guiding rollers RCV. (concentric) REV. (eccentric) are in contact with the raceways by 2 contact-points, hereby creating well constrained rollers on the raceway, both in radial and axial direction.
The Floating Rollers RCP. (concentric) REP. (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders. The roller can also rotate a little.
The Flat full Floating Rollers RCU. (concentric) REU. (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation. Being completely cylindrical It allows axial travel to be wider than R.P-version, but being free from lateral shoulders, it can run out of the rail or against the bottom rail,when exceeding the nominal floating capacity. The Roller can also rotate a little.
THE GUIDING SLIDERS RV
THE FLOATING SLIDERS RP
THE EXTRA FLOATING RU
THE ROTATING RA
By utilizing all guiding rollers, RV.,RVS. sliders are obtained. These sliders are completely constrained and will support loads and moments in all directions with the greatest capacity in the radial direction.
By utilizing all floating rollers RP.,RPS. sliders are obtained. These sliders are able to carry full radial load, while floating and rotating a bit, without affecting the preload or the smooth running quality, to eliminate eventual binding problems, typical for recirculating ball-bearing sliders.
By utilizing all full flat floating rollers RU., RUS sliders are obtained. These sliders are able to carry full radial load, while floating and rotating a bit, without affecting the preload or the smooth running quality, too eliminating eventual binding problems, typical for recirculating ball-bearing sliders. Extra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfaces. Being completely cylindrical, free from lateral shoulders, it can run out of the rail or against the bottom rail, when exceeding the nominal floating capacity. The slider can too rotate a bit.
By mixing guiding and floating rollers RA., RAS. sliders are obtained. These sliders are able to carry full radial load, while rotating a bit, without affecting the preload or the smooth running quality, meanwhile allowing for precise movement. These sliders also retain the ability to guide the payload as it travels. Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces, that cause traditional bearings to bind. New RAG/RAGS sliders with MRG43/46 rails offer greater rotation capacity, compared with RA sliders with MR43 rails.

MRG 18-43 RAILS TECHNICAL FEATURES The MRG Series Rails are available with two types of mounting holes: • MRG .. L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail. • MRG .. S with countersunk mounting holes for UNI-standard ISO5933 common screws . The rail has a “C” shaped cross-section with interior, convex raceways. The convex raceways are polished for smooth, low noise movement. The interior raceways are protected from accidental bumps and other damages, that might ruin the raceway surface. The shape also protects the rollers from similar types of damage. MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 2.0 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance. This treatment is not a plating which can flake off but instead penetrates and alters the material surface. The result is a very hard and durable, corrosion resistance linear rail, that is black in color, due to the micro impregnation of oil and antioxidants. VERSION WITH C’SUNK HOLES MRG..S

The raceways are still protected by the standard oxidation and raceway lubrication.
MRG 46 RAILS The new MRG46 rail differs from MRG43 rail, as having a thicker C-shaped raceways, to provide much greater inertial moment capacity, also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) , e.g. door fixed to the rail, while sliders and the fixed structure, so hereby the door flexion is a direct result of the rail’s innertial moment. The load capacity of the relative R.G46 and R.GS46 sliders are valid with completely fixed rail for its whole length, the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed. The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function.

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R, R.S SLIDERS The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers, according to different load capacities and fixing possibilities.
HIGH PERFORMANCE
The precision rollers are lubricated for life and with 2RS seals. The sliders come in version with 3 or 5 rollers, for which some with Eccentric pivot for preload setting. The sliders have mounted strong wipers with preoiled felt for good cleaning/lubrication of raceways to provide for long maintenance free operation.
22
The turning parts are all well protected within the internal raceways and between the wipers, to provide the markets most compact and well protected linear roller system. The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide, up to 10m / s, with a low noise level.The selfaligning compositions are illustrated in 14-17 pages
MR RAILS TECHNICAL FEATURES The MR Series Rails are available with two types of mounting holes: • MR .. L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail. • MR .. S with countersunk mounting holes for UNI-standard ISO5933 common screws . The rail has a “C” shaped cross-section with interior, convex raceways. The convex raceways are polished for smooth, low noise movement. The interior raceways are protected from accidental bumps and other damage, that might ruin the raceway surface. The shape also protects the rollers from similar types of damage. MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 1.0 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance. This treatment is not a plating which can flake off but instead penetrates and alters the material surface. The result is a very hard and durable, corrosion resistance linear rail, that is black in color, due to the micro impregnation of oil and antioxidants. VERSION WITH C’SUNK HOLES MR..S

LINEAR ROLLER SLIDES SERIES ML The ML Series Linear Roller System consists of a C shaped steel rail with internal concave raceways where robust ball bearing rollers travel. The high precision rollers are lubricated for life and protected with 2Z seals. Sliders are available with three or five rollers including eccentrics to adjust the slider’s preload. Both ends of the sliders are equipped with polyamide wipers to remove debris from the raceway and grease impregnated felt wipers to lubricate the raceways for long life with minimal maintenance.
STANDARD
Sliders include a mix of concentric and eccentric rollers. The eccentric rollers are used to preload the system and eliminate any play. The preload can be adjusted to suit the particular application. Sliders are able to carry load and moment loads in all direction. Because one of the rail raceways contacts more rollers than the other, this direction is the prefered direction of radial loading. Two small circular marks indicate the direction of preferred slider loading. The ML Systems’s C shaped steel rail has internal raceways that are protected from accidental damage. Similarly, the rollers are protected inside the rail and under the slider body. 26 Overall, the ML Systems is easy to assemble and extremely compact.
ML RAILS TECHNICAL FEATURES The ML Series Rails are available with two types of mounting holes: • ML .. L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail. • ML .. S with countersunk mounting holes for UNI-standard ISO5933 common screws . The rail has a “C” shaped cross-section with interior, convex raceways. The convex raceways are polished for smooth, low noise movement. The interior raceways are protected from accidental bumps and other damage, that might ruin the raceway surface. The shape also protects the rollers from similar types of damage. ML Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 1.0 high depth nitriding process and with afterwards black oxidation that provides an excellent corrosion resistance. This treatment is not a plating which can flake off but instead penetrates and alters the material surface. The result is a very hard and durable, corrosion resistant linear rail, that is black in color, due to the micro impregnation of oil and antioxidants. VERSION WITH C’SUNK HOLES ML..S

USE OF SINGLE WHEELS In addition to standard sliders, rollers can also be fitted to custom sliders or even directly to mobile elements. When doing so, the following points must be kept in mind:
PHASE 1-2
P
ROLLERS
The minimum number of rollers is 3. Of these, 2 must be concentric rollers and located to run in the raceway of the rail that supports the main load. The third must be an eccentric roller, adjusted to run along the opposite raceway. If more than two rollers are needed to support the main load, only two must be fixed, concentric rollers. Additional load-bearing rollers must be eccentric rollers adjusted to run on the same raceway. It is important to ensure that eccentric rollers used in this way are perfectly aligned in order to distribute load equally.
30
The arrangement and number of rollers must always be determined by the amount and direction of load applied by the element the rollers support. The overall load capacity of the assembly is limited by the maximum load capacity of the most highly loaded roller. The roller bearing that takes the greatest load should always be a concentric roller. T-RACE’s Technical Assistance Service is always happy to suggest the best arrangement of rollers for specific applications. If load is supported by more than two rollers (e.g. 3, 4 or 5) on the same raceway, and load is located centrally with respect to the set of rollers, total load capacity is determined by the load capacity of one roller multiplied by the total number of rollers, reduced by a suitable safety factor depending on the accuracy of alignment of the rollers and on the rigidity of the surface to which they are fixed.
Concentric
Concentric
P
At least one eccentric roller must be provided and adjusted to run on the opposite raceway in order to eliminate play. Additional rollers may be needed, on the basis of the direction of load. e.g. to counteract bi-directional or overhung loads. Eccentric rollers used in this way must be located as near as possible to a concentric roller. See the table alongside for minimum distances.

Holes in the mobile element intended to fix rollers in place must be of the bare minimum diameter necessary for the fixing screw to pass through and must be of the minimum length specified in the table. Fixing screws for eccentric rollers must always be fitted with a lock washer to permit adjustment of preload.
NO
The procedure for adjusting eccentric rollers is similar to that given on page 10 for standard sliders, as are screw tightening torques.
YES
ROLLERS FOR MRG RAILS The precision rollers R..G series for MRG rails have double-row ball-bearings to provide high-capacities, both in radial and axial direction. They are available in the guiding version R.VG series, with two contact points on the V-shaped roller raceway. Compared to rollers for MR rails, these new rollers have Gothic shaped raceways for improved performance. The Floating roller versions have one contact plane, the axial floating of the R.PG rollers are limited by the two lateral shoulders. The Extra floating rollers series R.UG have completely flat outer ring, without lateral support. The rollers are equipped with 2RS seals, nitrile rubber with reinforced metal core. The rollers are lubricated for life with lithium based grease. Inner and outer bearing rings are made of core hardened bearing steel, ground to DIN620 precision classes.

MAXIMUM LOAD CAPACITY
• The sliders are available in 3 and 5 rollers configuration. The 3 roller version has the two lateral rollers aligned and in contact with the same raceway. These two rollers are concentric and “fixed” - blocked with Loctite. The adjustable central roller is eccentric for preloading against the opposite raceway.
The sliders’ max. radial load capacities are given by the highest number of rollers aligned against the same raceway. As non symmetric roller positioning, the sliders must be positioned correctly during installation to obtain listed radial load capacities. Circular marks on the slider body, indicate the side with most rollers in contact with same raceway.
TECHNICAL FEATURES
• The 5 roller version has the two lateral and central roller aligned against the same raceway. These three rollers are “fixed”. The lateral are concentric rollers, while the central is an eccentric roller. The two adjustable rollers, next to the lateral roller, are eccentric and preloaded against the opposite raceway.

LAN40+LUN40 SELF-ALIGNING SYSTEM In two-slide linear motion systems, you can use one LAN40 rail with one LUN40 rail, with PAN40 sliders in both rails. This combination creates a self-aligning system capable of tolerating alignment errors of up to 3.4 mm.
LUN40 RAIL
LUN40 RAIL
COST EFFECTIVE
The sliders in the LAN40 guiding rail are rigidly connected, via the mobile element, to the sliders in the LUN40 floating rail on the other side. The LAN40 guiding rail ensures play-free linear motion (see the description of points of contact on page 5). The sliders in the LUN40 floating rail are therefore also play-free but able to move axially across the flat raceways. This system avoids overload on the sliders as the result of rail alignment error.
46
The limit of axial movement of PAN40 sliders towards the inside of LUN40 rails is determined by the size of the heads of the rail fixing screws (see figures below). In particular, T RACE’s special flat head DIN 7991 screws permit approximately 1 mm of extra axial movement compared to standard ISO 7380 screws.
Axial movement 3.4 mm
The limit of axial movement towards the outside of the LUN40 rail is determined by the point of departure of the roller from the raceway. The limit specified in the catalogue guarantees sufficient contact between rollers and raceway to support rated load. Sliders in LUN40 rails offer less load capacity than the same sliders in LAN40 rails. (See the table on page 41).
Permissible alignment error
Min - Max axial movement
Limit towards outside with full load capacity
Limit towards inside of rail with standard ISO 7380 screws
Limit towards inside of rail with TORX DIN 7991 screws
ROLLERS FOR LAN AND LUN SERIES RAILS
All our rollers are made from core tempered and precision ground bearing grade carbon steel. Rollers are of the single row ball bearing type, with the balls held in place by a metal cage. Precision ground surfaces ensure a smooth, silent rolling action. Rollers are also fitted with 2Z rated metal shields to protect the ball bearings raceway and ensure good resistance to high temperatures. The ball bearing is lubricated for life with a wide temperature ranging lithium soap grease. The mounting axle is made in one piece with the inner bearing, for maximum strength. Rollers come in two types: eccentric and concentric. PEN and PCN series rollers for size 26 and 40 rails have a hexagonal recess for an Allen key in the side opposite the threaded fixing hole. This serves to hold the axle steady while the fixing screw is being tightened with a second Allen key. On eccentric rollers, it also serves to adjust roller position, so as to reach the desired preload setting. PEV and PCV rollers for size 30 rails have a special central square pivot accessible with a flat key, inserted between slider body and eccentric rollers. The flat key is supplied by T RACE.

ROLLERS
As an alternative to our standard 3 and 5-roller sliders, rollers for use with LAN and LUN rails can also be mounted on custom sliders or directly on the mobile element. In such cases, the number, arrangement and types of roller need to be chosen to match the requirements of the application. See page 30 for assembly and adjustment instructions.

SELF-ALIGNING COMBINATIONS When the FXRG rails are used in parallel, use of floating rollers R.P43G and guiding rollers R.V43G provide a Self-aligning system, capable of compensating greate inaccuracies of structure or assembly errors. When the guiding rollers R.VG43 are in contact with the FXRG’s gothic raceways, the rollers assure precise guiding and meanwhile also compensation for some misalignment, as able to rotate slightly around its longitudinal axis of about +/- 5 °. Combined with floating rollers R.PG43 on a parallel rail, such system can compensate an axial displacement of +/- 1 mm , in addition to a max. rotation of +/- 5 °.
The combination effect of both rotation and lateral movement, allow two parallel rails to compensate for misalignment on both a) and b) level .
ROLLERS
Only for ROTELLE R..43G

MOUNTING CONFIGURATIONS
The concentric rollers should be positioned in the direction of radial loading. Warning! A single slider configuration will rotate +/- 5° around the longitudinal axis of a single FXRG rail, not able to take any Mx moments.

52
Eccentric rollers REVG43
It is recommended in the case of use of more than two rollers on the same track with max. radial load, to use only two concentric rollers (as from example figure). The other rollers are recommended to be eccentric rollers. For cases with a wider distance between the concentric rollers, possible with all concentric rollers, contact T RACE’s Technical Office for dimensioning.

MOUNTING CONFIGURATIONS The rollers need to be positioned on the rail in numbers and directions according to the prevailing load. The rollers’ load capacity is shown on page 51. It is always preferable to orient the rollers so that the prevailing load acts radially on the rollers, due to higher radial load capacity, than axial load capacity.
Co rad
The rollers must be fixed on a metal surface not yielding, perfectly flat and with its fixing screws, applying a locking torque of 22 Nm. The tightening of the fixing-screw is to be performed, while holding the roller firm with an Allen-wrench, present on the opposite side of the fixing thread. In case eccentric rollers, it is advisable to use a cup-spring washer under the screw-head to obtain a firm movement, able to maintain the roller “firm” against the surface and facilitate minor adjustment of eccentric roller, before the final locking.
TECHNICAL FEATURES

53
The preload adjustment can also be carried out by checking the force Fi of insertion of the movable part, in which the rollers are fixed into the rail. In general for a good Fi adjustment, the inserting friction must be between 2-10 N. To increase or decrease the Fi act on eccentric rollers, opposite to the load direction (see figure below).

Standard Allen-key Configutation possibilities
In case required to have eccentric rollers on the internal rail side, it is necessary to include optional accesses, needed to allow Allen-key to reach roller. Otherwise the adjustment can take place outside of the rail.
“HIGH LOAD” BALLCAGE SLIDES - SF SERIES BALLCAGE LINEAR GUIDES The SF series is a linear guide, formed by one or more sliders moving within a ballcage, inbetween the rail’s raceways. The components are the same as the SR series, with the same excellent characteristics.

CONFIGURATIONS
SF STANDARD The SF series is a linear guide formed by one moving slider within one ballcage. The stroke is limited by the ballcage length and the rail length. Available a large number of standard combinations of rail and slider lengths.
55
SF WITH DOUBLE SLIDER IN THE SAME BALLCAGE The SF ballcage slides can be configured on request with two sliders spaced apart within the same ballcage. This configuration is useful when the length of the mobile starts is important. The size of sliders and length of rails can be chosen from standard SF series.
SF WITH DOUBLE SLIDER IN SEPARATE BALLCAGES The SF ballcage slides can be configured on request with two sliders in two separate ballcages. This allow independent movements of the two sliders in opposite directions, for example for sliding door the opening with two panels which converge in closing. The size of sliders and length of rails can be chosen from standard SF series.

LUBRICATION AND USE OF WIPERS All sliders are supplied complete with wipers containing a synthetic felt soaked in lubricating oil, which release a thin lubricating film on the raceways for long period of proper operation. The period of self-lubrication depends on conditions of use, level of environmental pollution.
LUBRICATION
In most normal conditions, the self-lubricating wipers can last up to 1000 km. They can be easily replaced with a replacement kit of 10 wipers per kit, see table .The rollers are lubricated for life with grease lithium soaps and with 2RS or 2Z lateral seals, depending on version. Correct lubrication is very important to ensure a long lifetime. For applications with high frequency is recommended to clean and regrease the rail’s raceways periodically every year or every 200,000 cycles ,depending on the operation environment. We recommend using high pressure grease fat class NLGI2(ISO2137)

SIZING VERIFICATION After identifying the most appropriate positioning of rails and sliders, or eventually the single rollers, it is necessary to verify the proper sizing of the linear components. This both from a static point of view and in accordance to the expected life-time. For the static verification it is necessary to determine the load on each slider or roller, and then identify the most stressed one. Then verify the values of the safety coefficients, while comparing with the max. nominal load capacities. When the applied load is a combination of loads; radial and/or axial loads and moments, it is necessary to determine the value of each factor and verify that:
+
Prad Co rad
Mex Mx
+ = = = = = = =
Pax Prad Mex, Mey, Mez Co ax Co rad Mx, My, Mz Z
Mey My
+
+
Mez Mz
= 1
Z
NOTE: Co rad, the radial load capacity for the sliders is to be understood only indirection shown on the slider body with two circular imprints.
Application conditions
1-1,5
Accurate determination of static and dynamic loads. Precise assembly, tight structure.
1,5-2
Avarage conditions
2-3,5
Insufficient determination of applied loads. Vibrations, loose structure. Imprecise assembly. Unfavourable invironmental conditions.
59
THEORETICAL LIFETIME CALCULATION The theoretical life of the rollers and raceways of rail should be determined by the conventional formula as indicated below in km of running, however it should be kept in mind, that the value thus calculated must be taken with caution just for orientation, in fact, the real service life achieved can be very different from that calculated value, because the phenomena of wear and fatigue are caused by factors not easy to predetermine, for example: • Inaccuracy in the estimation of the real loading condition • Overloading for inaccuracies assembly • Vibration, shock and dynamic pulse stress • Raceways status of lubrication
• Thermal excursions • Environmental pollution and dust • Damage mounting • Stroke length and frequency of movement The equivalent load applied on the most stressed slider = P , is determined by below formula:
L (Km)= 100 •

T RACE’s range of linear bearings are setting new standards due to their innovative design and technical concepts. The family MONORACE, based on different C-shaped rails with a wide range of sliders, is offering unique linear solutions for all kinds of automation applications for many industries. T RACE’s system with roller sliders and internal raceways, offer the markets highest performing system, along with being size wise the most compact system.
HIGH PERFORMANCE The new rails MRG series rails are the evolution of the consolidated MR series. The new rails have a number of improvements related to the contact geometries, new materials for increased strength and depth of hardening - T RACE-NOX 2.0 last generation hardening treatments, showing our commitment to continuous technological improvement of T RACE products. The new MRG43 is companied with a new version MRG46 with increased thicknesses of the flanges to achieve a more rigid rail for critical application, where the rail becomes a self-supporting part of the structure. The MRG and MR rails allow combinations of different sliders to obtain self-aligning systems based on pairs of rails. Such self-aligning system is able to compensate for surface assembly inaccuracies on longitudinal and transverse plane, like non precise carpentry, aluminum structures or bent sheet metal structures, hereby avoiding costly processing / machining to achieve precise parallel rail installation. The internal raceways with protected roller wheels, along with lateral seals and strong wipers, incorporating preoiled felts makes the MONORACE linear system very suitable for even harsh ambients, dust, humidity etc. The rollers of large diameter are rarely sensitive to impurities entering the linear system. STANDARD The ML series rail represents a simplified version of the MR series with similar dimensions. The thinner C shaped rails have the concave inner raceways in which slide rollers of single row bearing with shields and inner ball cage made in metal. The carriages in various versions are equipped with wipers with lubricating felt. The ML series does not provide self-aligning features COST EFFECTIVE LAN rails are made from sheet steel and shaped by high precision, ultra-smooth forming rollers. They are then case hardened using our revolutionary TRACE-NOX nitriding and black oxidising process to ensure an extended lifetime and excellent corrosion resistance. The slider bodies are cataphoretically blackened for maximum corrosion resistance. The rollers are made from core tempered and precision ground, bearing grade steel. The ball bearings are lubricated for life with wide temperature range bearing grease and protected by 2Z rated metal shields. Robust elastomer raceway wipers are fitted at both ends of the slider to protect the rollers and keep the raceways clean. The wipers incorporate oil-impregnated felt pads to keep the points of contact between raceway and roller properly lubricated, for the lifetime of the rail. Wipers are held in place by a simple clip and can be removed and replaced easily. INOX LAX series rails and PAX series sliders are constructed entirely of stainless steel and are a simple and functional solution for applications that require high corrosion resistance,. The rails and sliders bodies are made from 300 Series stainless with rollers made from 440C. These are particularly suitable for food processing, pharmaceutical, and medical applications or in difficult environments such as marine environments where there is exposure to highly corrosive agents. The slider is equipped with 3 rollers. The middle roller is eccentric and is used to adjust the slider preload. The sliders are easily washable for applications subject to frequent cleaning and do not release particles into the environment and are particularly suitable for clean rooms. They are available in two sections: 26 and 40 mm.
The roller linear MODULAR system FLEXRACE offers the maximum flexibility configuration due to the original shape of the guide FXRG, basic component of the system, shaped with 3 raceways arranged at 90 ° to each other on which can slide the rollers R..G 43 series indifferently on each of the three raceways. The using of the single guide or two or more parallel guides gives rise to a number of combinations capable of satisfying each specific need for linear motion and offering exceptional ability to self-alignment. Like the MONORACE’s MR & ML rails, FXRG rail is constructed in high strength steel hardened with the last generation T RACE NOX 2.0 hardening treatments, for a further improvement of the performance and durability.
The ball cage linear slide HIGH LOAD of SF series offers a very high load capacity in a compact size. They are built from the base of the rail ML series with one or more sliders that move through the interposition of one or more robust ball cages with large diameter balls. Like the MONORACE rails are made by the same production process and hardened with thermochemical process patented T RACE NOX 1.0. They are suitable for horizontal movements with high loads in all directions and for movements where the stroke available is completely used.
GENERAL CHARACTERISTICS
The rails of MRG, MR and ML series are high precision cold drawn profiles, made from steel alloy that with our patented T RACE NOX thermo-chemical hardening process provide a very hard surface for high wear resistance, along with and at the same time a good protection against corrosion, even in critical environments.

TECHNICAL FEATURES
ROLLER POSITIONING Sliders are available with either 3 or 5 rollers. For the 3 roller version, the first and third roller are fixed concentric rollers that run on the same raceway. The second roller is eccentric and runs on the opposite raceway. The eccentric feature is used to adjust the slider preload in the rail. For the 5 roller version, the two lateral and the central roller are fixed, and run on the same raceway. The second and fourth roller are eccentric and run on the opposite raceway. The eccentric feature is used to adjust the slider preload in the rail. Because one raceway contacts more rollers than the other raceway, the sliders have a preferred loading direction. The slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading. Care during assembly is required to ensure the maximum load capacity of the system is achieved.
3-ROLLER SLIDER
5-ROLLER SLIDER 14
RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the rail’s raceways.
The guiding rollers RCV. (concentric) REV. (eccentric) are in contact with the raceways by 2 contact-points, hereby creating well constrained rollers on the raceway, both in radial and axial direction.
The Floating Rollers RCP. (concentric) REP. (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders. The roller can also rotate a little.
The Flat full Floating Rollers RCU. (concentric) REU. (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation. Being completely cylindrical It allows axial travel to be wider than R.P-version, but being free from lateral shoulders, it can run out of the rail or against the bottom rail,when exceeding the nominal floating capacity. The Roller can also rotate a little.
THE GUIDING SLIDERS RV
THE FLOATING SLIDERS RP
THE EXTRA FLOATING RU
THE ROTATING RA
By utilizing all guiding rollers, RV.,RVS. sliders are obtained. These sliders are completely constrained and will support loads and moments in all directions with the greatest capacity in the radial direction.
By utilizing all floating rollers RP.,RPS. sliders are obtained. These sliders are able to carry full radial load, while floating and rotating a bit, without affecting the preload or the smooth running quality, to eliminate eventual binding problems, typical for recirculating ball-bearing sliders.
By utilizing all full flat floating rollers RU., RUS sliders are obtained. These sliders are able to carry full radial load, while floating and rotating a bit, without affecting the preload or the smooth running quality, too eliminating eventual binding problems, typical for recirculating ball-bearing sliders. Extra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfaces. Being completely cylindrical, free from lateral shoulders, it can run out of the rail or against the bottom rail, when exceeding the nominal floating capacity. The slider can too rotate a bit.
By mixing guiding and floating rollers RA., RAS. sliders are obtained. These sliders are able to carry full radial load, while rotating a bit, without affecting the preload or the smooth running quality, meanwhile allowing for precise movement. These sliders also retain the ability to guide the payload as it travels. Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces, that cause traditional bearings to bind. New RAG/RAGS sliders with MRG43/46 rails offer greater rotation capacity, compared with RA sliders with MR43 rails.

L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail. • MRG .. S with countersunk mounting holes for UNI-standard ISO5933 common screws . The rail has a “C” shaped cross-section with interior, convex raceways. The convex raceways are polished for smooth, low noise movement. The interior raceways are protected from accidental bumps and other damages, that might ruin the raceway surface. The shape also protects the rollers from similar types of damage. MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 2.0 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance. This treatment is not a plating which can flake off but instead penetrates and alters the material surface. The result is a very hard and durable, corrosion resistance linear rail, that is black in color, due to the micro impregnation of oil and antioxidants. VERSION WITH C’SUNK HOLES MRG..S

MRG 46 RAILS The new MRG46 rail differs from MRG43 rail, as having a thicker C-shaped raceways, to provide much greater inertial moment capacity, also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) , e.g. door fixed to the rail, while sliders and the fixed structure, so hereby the door flexion is a direct result of the rail’s innertial moment. The load capacity of the relative R.G46 and R.GS46 sliders are valid with completely fixed rail for its whole length, the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed. The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function.

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R, R.S SLIDERS The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers, according to different load capacities and fixing possibilities.
HIGH PERFORMANCE
The precision rollers are lubricated for life and with 2RS seals. The sliders come in version with 3 or 5 rollers, for which some with Eccentric pivot for preload setting. The sliders have mounted strong wipers with preoiled felt for good cleaning/lubrication of raceways to provide for long maintenance free operation.
22
The turning parts are all well protected within the internal raceways and between the wipers, to provide the markets most compact and well protected linear roller system. The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide, up to 10m / s, with a low noise level.The selfaligning compositions are illustrated in 14-17 pages
MR RAILS TECHNICAL FEATURES The MR Series Rails are available with two types of mounting holes: • MR .. L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail. • MR .. S with countersunk mounting holes for UNI-standard ISO5933 common screws .

The interior raceways are protected from accidental bumps and other damage, that might ruin the raceway surface. The shape also protects the rollers from similar types of damage. MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 1.0 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance. This treatment is not a plating which can flake off but instead penetrates and alters the material surface. The result is a very hard and durable, corrosion resistance linear rail, that is black in color, due to the micro impregnation of oil and antioxidants. VERSION WITH C’SUNK HOLES MR..S

LINEAR ROLLER SLIDES SERIES ML The ML Series Linear Roller System consists of a C shaped steel rail with internal concave raceways where robust ball bearing rollers travel. The high precision rollers are lubricated for life and protected with 2Z seals. Sliders are available with three or five rollers including eccentrics to adjust the slider’s preload. Both ends of the sliders are equipped with polyamide wipers to remove debris from the raceway and grease impregnated felt wipers to lubricate the raceways for long life with minimal maintenance.
STANDARD
Sliders include a mix of concentric and eccentric rollers. The eccentric rollers are used to preload the system and eliminate any play. The preload can be adjusted to suit the particular application. Sliders are able to carry load and moment loads in all direction. Because one of the rail raceways contacts more rollers than the other, this direction is the prefered direction of radial loading. Two small circular marks indicate the direction of preferred slider loading. The ML Systems’s C shaped steel rail has internal raceways that are protected from accidental damage. Similarly, the rollers are protected inside the rail and under the slider body. 26 Overall, the ML Systems is easy to assemble and extremely compact.
ML RAILS TECHNICAL FEATURES The ML Series Rails are available with two types of mounting holes: • ML .. L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail. • ML .. S with countersunk mounting holes for UNI-standard ISO5933 common screws . The rail has a “C” shaped cross-section with interior, convex raceways. The convex raceways are polished for smooth, low noise movement. The interior raceways are protected from accidental bumps and other damage, that might ruin the raceway surface. The shape also protects the rollers from similar types of damage. ML Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 1.0 high depth nitriding process and with afterwards black oxidation that provides an excellent corrosion resistance. This treatment is not a plating which can flake off but instead penetrates and alters the material surface. The result is a very hard and durable, corrosion resistant linear rail, that is black in color, due to the micro impregnation of oil and antioxidants. VERSION WITH C’SUNK HOLES ML..S

USE OF SINGLE WHEELS In addition to standard sliders, rollers can also be fitted to custom sliders or even directly to mobile elements. When doing so, the following points must be kept in mind:
PHASE 1-2
P
ROLLERS
The minimum number of rollers is 3. Of these, 2 must be concentric rollers and located to run in the raceway of the rail that supports the main load. The third must be an eccentric roller, adjusted to run along the opposite raceway. If more than two rollers are needed to support the main load, only two must be fixed, concentric rollers. Additional load-bearing rollers must be eccentric rollers adjusted to run on the same raceway. It is important to ensure that eccentric rollers used in this way are perfectly aligned in order to distribute load equally.
30
The arrangement and number of rollers must always be determined by the amount and direction of load applied by the element the rollers support. The overall load capacity of the assembly is limited by the maximum load capacity of the most highly loaded roller. The roller bearing that takes the greatest load should always be a concentric roller. T-RACE’s Technical Assistance Service is always happy to suggest the best arrangement of rollers for specific applications. If load is supported by more than two rollers (e.g. 3, 4 or 5) on the same raceway, and load is located centrally with respect to the set of rollers, total load capacity is determined by the load capacity of one roller multiplied by the total number of rollers, reduced by a suitable safety factor depending on the accuracy of alignment of the rollers and on the rigidity of the surface to which they are fixed.
Concentric
Concentric
P
At least one eccentric roller must be provided and adjusted to run on the opposite raceway in order to eliminate play. Additional rollers may be needed, on the basis of the direction of load. e.g. to counteract bi-directional or overhung loads. Eccentric rollers used in this way must be located as near as possible to a concentric roller. See the table alongside for minimum distances.

Holes in the mobile element intended to fix rollers in place must be of the bare minimum diameter necessary for the fixing screw to pass through and must be of the minimum length specified in the table. Fixing screws for eccentric rollers must always be fitted with a lock washer to permit adjustment of preload.
NO
The procedure for adjusting eccentric rollers is similar to that given on page 10 for standard sliders, as are screw tightening torques.
YES
ROLLERS FOR MRG RAILS The precision rollers R..G series for MRG rails have double-row ball-bearings to provide high-capacities, both in radial and axial direction. They are available in the guiding version R.VG series, with two contact points on the V-shaped roller raceway. Compared to rollers for MR rails, these new rollers have Gothic shaped raceways for improved performance. The Floating roller versions have one contact plane, the axial floating of the R.PG rollers are limited by the two lateral shoulders. The Extra floating rollers series R.UG have completely flat outer ring, without lateral support. The rollers are equipped with 2RS seals, nitrile rubber with reinforced metal core. The rollers are lubricated for life with lithium based grease. Inner and outer bearing rings are made of core hardened bearing steel, ground to DIN620 precision classes.

MAXIMUM LOAD CAPACITY
• The sliders are available in 3 and 5 rollers configuration. The 3 roller version has the two lateral rollers aligned and in contact with the same raceway. These two rollers are concentric and “fixed” - blocked with Loctite. The adjustable central roller is eccentric for preloading against the opposite raceway.
The sliders’ max. radial load capacities are given by the highest number of rollers aligned against the same raceway. As non symmetric roller positioning, the sliders must be positioned correctly during installation to obtain listed radial load capacities. Circular marks on the slider body, indicate the side with most rollers in contact with same raceway.
TECHNICAL FEATURES
• The 5 roller version has the two lateral and central roller aligned against the same raceway. These three rollers are “fixed”. The lateral are concentric rollers, while the central is an eccentric roller. The two adjustable rollers, next to the lateral roller, are eccentric and preloaded against the opposite raceway.

The two inclined bearing slopes run on the two slopes of the V-shaped raceways of the LAN rail. These 2 points contact on each roller in upper or lower raceway, assure both radial and axial load capacity.
LUN FLOATING RAIL
The flat central surface of the roller runs on the flat raceway of the LUN rail. This one point contact of each roller in upper or lower raceway, provide only radial load capacity, but allows for axial floating capability.
RAILS SERIES LAN AND LUN “NITRIDE” DESIGN • Our new LAN and LUN series rails are made from sheet steel and shaped by high precision, ultra-smooth forming rollers. They are then fully nitrided, black oxidised and impregnated with rust inhibitor for maximum corrosion resistance. RAIL MOUNTING HOLES • Rail mounting holes have an 80 mm pitch.

LAN40+LUN40 SELF-ALIGNING SYSTEM In two-slide linear motion systems, you can use one LAN40 rail with one LUN40 rail, with PAN40 sliders in both rails. This combination creates a self-aligning system capable of tolerating alignment errors of up to 3.4 mm.
LUN40 RAIL
LUN40 RAIL
COST EFFECTIVE
The sliders in the LAN40 guiding rail are rigidly connected, via the mobile element, to the sliders in the LUN40 floating rail on the other side. The LAN40 guiding rail ensures play-free linear motion (see the description of points of contact on page 5). The sliders in the LUN40 floating rail are therefore also play-free but able to move axially across the flat raceways. This system avoids overload on the sliders as the result of rail alignment error.
46
The limit of axial movement of PAN40 sliders towards the inside of LUN40 rails is determined by the size of the heads of the rail fixing screws (see figures below). In particular, T RACE’s special flat head DIN 7991 screws permit approximately 1 mm of extra axial movement compared to standard ISO 7380 screws.
Axial movement 3.4 mm
The limit of axial movement towards the outside of the LUN40 rail is determined by the point of departure of the roller from the raceway. The limit specified in the catalogue guarantees sufficient contact between rollers and raceway to support rated load. Sliders in LUN40 rails offer less load capacity than the same sliders in LAN40 rails. (See the table on page 41).

ROLLERS FOR LAN AND LUN SERIES RAILS
All our rollers are made from core tempered and precision ground bearing grade carbon steel. Rollers are of the single row ball bearing type, with the balls held in place by a metal cage. Precision ground surfaces ensure a smooth, silent rolling action. Rollers are also fitted with 2Z rated metal shields to protect the ball bearings raceway and ensure good resistance to high temperatures. The ball bearing is lubricated for life with a wide temperature ranging lithium soap grease. The mounting axle is made in one piece with the inner bearing, for maximum strength. Rollers come in two types: eccentric and concentric. PEN and PCN series rollers for size 26 and 40 rails have a hexagonal recess for an Allen key in the side opposite the threaded fixing hole. This serves to hold the axle steady while the fixing screw is being tightened with a second Allen key. On eccentric rollers, it also serves to adjust roller position, so as to reach the desired preload setting. PEV and PCV rollers for size 30 rails have a special central square pivot accessible with a flat key, inserted between slider body and eccentric rollers. The flat key is supplied by T RACE.

ROLLERS
As an alternative to our standard 3 and 5-roller sliders, rollers for use with LAN and LUN rails can also be mounted on custom sliders or directly on the mobile element. In such cases, the number, arrangement and types of roller need to be chosen to match the requirements of the application. See page 30 for assembly and adjustment instructions.

SELF-ALIGNING COMBINATIONS When the FXRG rails are used in parallel, use of floating rollers R.P43G and guiding rollers R.V43G provide a Self-aligning system, capable of compensating greate inaccuracies of structure or assembly errors. When the guiding rollers R.VG43 are in contact with the FXRG’s gothic raceways, the rollers assure precise guiding and meanwhile also compensation for some misalignment, as able to rotate slightly around its longitudinal axis of about +/- 5 °. Combined with floating rollers R.PG43 on a parallel rail, such system can compensate an axial displacement of +/- 1 mm , in addition to a max. rotation of +/- 5 °.
The combination effect of both rotation and lateral movement, allow two parallel rails to compensate for misalignment on both a) and b) level .
ROLLERS
Only for ROTELLE R..43G

MOUNTING CONFIGURATIONS
The concentric rollers should be positioned in the direction of radial loading. Warning! A single slider configuration will rotate +/- 5° around the longitudinal axis of a single FXRG rail, not able to take any Mx moments.

52
Eccentric rollers REVG43
It is recommended in the case of use of more than two rollers on the same track with max. radial load, to use only two concentric rollers (as from example figure). The other rollers are recommended to be eccentric rollers. For cases with a wider distance between the concentric rollers, possible with all concentric rollers, contact T RACE’s Technical Office for dimensioning.

MOUNTING CONFIGURATIONS The rollers need to be positioned on the rail in numbers and directions according to the prevailing load. The rollers’ load capacity is shown on page 51. It is always preferable to orient the rollers so that the prevailing load acts radially on the rollers, due to higher radial load capacity, than axial load capacity.
Co rad
The rollers must be fixed on a metal surface not yielding, perfectly flat and with its fixing screws, applying a locking torque of 22 Nm. The tightening of the fixing-screw is to be performed, while holding the roller firm with an Allen-wrench, present on the opposite side of the fixing thread. In case eccentric rollers, it is advisable to use a cup-spring washer under the screw-head to obtain a firm movement, able to maintain the roller “firm” against the surface and facilitate minor adjustment of eccentric roller, before the final locking.
TECHNICAL FEATURES

53
The preload adjustment can also be carried out by checking the force Fi of insertion of the movable part, in which the rollers are fixed into the rail. In general for a good Fi adjustment, the inserting friction must be between 2-10 N. To increase or decrease the Fi act on eccentric rollers, opposite to the load direction (see figure below).

Standard Allen-key Configutation possibilities
In case required to have eccentric rollers on the internal rail side, it is necessary to include optional accesses, needed to allow Allen-key to reach roller. Otherwise the adjustment can take place outside of the rail.
“HIGH LOAD” BALLCAGE SLIDES - SF SERIES BALLCAGE LINEAR GUIDES The SF series is a linear guide, formed by one or more sliders moving within a ballcage, inbetween the rail’s raceways. The components are the same as the SR series, with the same excellent characteristics.

CONFIGURATIONS
SF STANDARD The SF series is a linear guide formed by one moving slider within one ballcage. The stroke is limited by the ballcage length and the rail length. Available a large number of standard combinations of rail and slider lengths.
55
SF WITH DOUBLE SLIDER IN THE SAME BALLCAGE The SF ballcage slides can be configured on request with two sliders spaced apart within the same ballcage. This configuration is useful when the length of the mobile starts is important. The size of sliders and length of rails can be chosen from standard SF series.
SF WITH DOUBLE SLIDER IN SEPARATE BALLCAGES The SF ballcage slides can be configured on request with two sliders in two separate ballcages. This allow independent movements of the two sliders in opposite directions, for example for sliding door the opening with two panels which converge in closing. The size of sliders and length of rails can be chosen from standard SF series.

LUBRICATION AND USE OF WIPERS All sliders are supplied complete with wipers containing a synthetic felt soaked in lubricating oil, which release a thin lubricating film on the raceways for long period of proper operation. The period of self-lubrication depends on conditions of use, level of environmental pollution.
LUBRICATION
In most normal conditions, the self-lubricating wipers can last up to 1000 km. They can be easily replaced with a replacement kit of 10 wipers per kit, see table .The rollers are lubricated for life with grease lithium soaps and with 2RS or 2Z lateral seals, depending on version. Correct lubrication is very important to ensure a long lifetime. For applications with high frequency is recommended to clean and regrease the rail’s raceways periodically every year or every 200,000 cycles ,depending on the operation environment. We recommend using high pressure grease fat class NLGI2(ISO2137)

SIZING VERIFICATION After identifying the most appropriate positioning of rails and sliders, or eventually the single rollers, it is necessary to verify the proper sizing of the linear components. This both from a static point of view and in accordance to the expected life-time. For the static verification it is necessary to determine the load on each slider or roller, and then identify the most stressed one. Then verify the values of the safety coefficients, while comparing with the max. nominal load capacities. When the applied load is a combination of loads; radial and/or axial loads and moments, it is necessary to determine the value of each factor and verify that:

THEORETICAL LIFETIME CALCULATION The theoretical life of the rollers and raceways of rail should be determined by the conventional formula as indicated below in km of running, however it should be kept in mind, that the value thus calculated must be taken with caution just for orientation, in fact, the real service life achieved can be very different from that calculated value, because the phenomena of wear and fatigue are caused by factors not easy to predetermine, for example: • Inaccuracy in the estimation of the real loading condition • Overloading for inaccuracies assembly • Vibration, shock and dynamic pulse stress • Raceways status of lubrication
• Thermal excursions • Environmental pollution and dust • Damage mounting • Stroke length and frequency of movement The equivalent load applied on the most stressed slider = P , is determined by below formula:
