LINEAR BEARINGS TYPE RSD
ASSEMBLY PROCEDURE BEFORE START ASSEMBLY PM linear bearings are precision components; they have to be handled with meticulous care. To achieve a perfect linear bearing, please pay due attention to the following notes: • Be careful in handling the components. Do not drop it or hit it with anything like a hammer. Damages on the rail surface will have his impact on the running performance and operation life. • Keep out any foreign material when mounting the rails. • During assembly, all linear bearing components must have the same room temperature. • For an uniform tightening of the bolts the use of a torque screw driver is recommended. Various models and bits are available. Please consult PM.

against the mounting and reference shoulder. They should then be bolted down by tightening up progressively, starting from one end and working to the other. Parallelism of the V-tracks of the rails (ΔA and ΔB ) should be checked. The tolerance must be within the tolerance of the linear bearings (page 14). When this has been done, the slide element in question is now ready for assembly.

4.1) The slide top can now be assembled. The fixed bearing rail (2) should be mounted as described at 3.1 above, but the adjustable rail (3) should only be screwed down lightly, to leave a gap between V-tracks for the insertion of ball-, roller- or needle cages. 5) This point only in cases where end stops are already inserted in the rail ends. Remove the end stop screws. 6) Carefully insert the cages. When the cages are exact in position, bolt down the adjustable V-rail lightly, until the screws are finger-tight. 7) Fit the end stop screws or end pieces. 8) The linear bearing set can now be play-free adjusted using the lateral preload setscrews.(chapter Preload Setting Linear Bearings, page 18). 9) Secure the attachment screws on the adjusting rail. 10) When assembly is finished, the linear bearings must be inspected for absence of play and for running the accuracy.

For a satisfying installation of all types of linear bearings in this catalog, the following should be observed: 1) Fixing holes in the support structure(slide-base) should be “spotted through” from the holes in the rails. This is highly desirable as the original pitch of individual holes may have altered during hardening by as much as 0.4 mm. To compensate this, in part at least, special attachment screws type GD or GDN can be supplied. The dimensions of these are listed in the tables under the relative linear bearings for sizes. 2) Carefully de-burr and clean all constructional elements, to ensure a flat surface and a perfect seating of the rails. 3) The inner rail-pair (1), mounted “shoulder-toshoulder” should be bolted down first, as follows: The base and reference face1 of the linear bearing rails should be lightly oiled before they are clamped

Linear bearings type RSD are compact guides for precise linear motion providing high accuracy and an outstanding reliability. Depending on the load requirements they can be fitted either with ball or roller cages. With many years of experience RSD-bearings are the world-wide standard in hightech applications requiring first class performances and quality with minimum cost.
STRUCTURE AND FEATURES
NOTES BY ORDERING
Depending on the construction, the linear bearing can be fitted with ball- or roller cages with alternately crossed rollers. The construction consists of two pairs linear bearings; one pair consists of two similar 90° V-groove rails, through-hardened and precision ground, fitted with a cage in-between. Crossed roller cages are used in highload and high-precision applications (note: good dust protection is in this case required). Cages fitted with balls are used in applications which require less capacity, low friction resistance, or where dust and dirt are likely to penetrate into the rails (balls are affected less by dust or dirt, due to a self-cleaning effect of the balls).
One set linear bearings RSD consists of: 4 pcs. rails (=2 pairs), 2 pcs. cages and 8 pcs. end screws. By ordering please specify the following: • Quantity and type of rails • Quantity, type and length of cages or max. stroke • Direction of movement (eg: horizontal, vertical or in-between) • Quantity and type of end screws or end pieces with or without wipers. (in case of GC and GC-A, only 4 pcs are needed) Example: To order one linear bearing set of 300 mm length, size 6 mm for a 120 mm long horizontal stroke in standard quality please specify. • 4 pcs. rails RSD-6300 • 2 pcs. roller cages R6x20AA • 8 pcs. end screws GA-6
Rails are equipped with countersunk attachment holes, bored according to a standard configuration. Threaded holes in ends for fixing end pieces and wipers. For the attachment of the rails, special screws type GD can be ordered separately. (see page 35) On request we supply linear bearings with roller size ø 18 mm and ø 24 mm.

ASSEMBLY PROCEDURE BEFORE START ASSEMBLY PM linear bearings are precision components; they have to be handled with meticulous care. To achieve a perfect linear bearing, please pay due attention to the following notes: • Be careful in handling the components. Do not drop it or hit it with anything like a hammer. Damages on the rail surface will have his impact on the running performance and operation life. • Keep out any foreign material when mounting the rails. • During assembly, all linear bearing components must have the same room temperature. • For an uniform tightening of the bolts the use of a torque screw driver is recommended. Various models and bits are available. Please consult PM.

against the mounting and reference shoulder. They should then be bolted down by tightening up progressively, starting from one end and working to the other. Parallelism of the V-tracks of the rails (ΔA and ΔB ) should be checked. The tolerance must be within the tolerance of the linear bearings (page 14). When this has been done, the slide element in question is now ready for assembly.

4.1) The slide top can now be assembled. The fixed bearing rail (2) should be mounted as described at 3.1 above, but the adjustable rail (3) should only be screwed down lightly, to leave a gap between V-tracks for the insertion of ball-, roller- or needle cages. 5) This point only in cases where end stops are already inserted in the rail ends. Remove the end stop screws. 6) Carefully insert the cages. When the cages are exact in position, bolt down the adjustable V-rail lightly, until the screws are finger-tight. 7) Fit the end stop screws or end pieces. 8) The linear bearing set can now be play-free adjusted using the lateral preload setscrews.(chapter Preload Setting Linear Bearings, page 18). 9) Secure the attachment screws on the adjusting rail. 10) When assembly is finished, the linear bearings must be inspected for absence of play and for running the accuracy.

For a satisfying installation of all types of linear bearings in this catalog, the following should be observed: 1) Fixing holes in the support structure(slide-base) should be “spotted through” from the holes in the rails. This is highly desirable as the original pitch of individual holes may have altered during hardening by as much as 0.4 mm. To compensate this, in part at least, special attachment screws type GD or GDN can be supplied. The dimensions of these are listed in the tables under the relative linear bearings for sizes. 2) Carefully de-burr and clean all constructional elements, to ensure a flat surface and a perfect seating of the rails. 3) The inner rail-pair (1), mounted “shoulder-toshoulder” should be bolted down first, as follows: The base and reference face1 of the linear bearing rails should be lightly oiled before they are clamped

Linear bearings type RSD are compact guides for precise linear motion providing high accuracy and an outstanding reliability. Depending on the load requirements they can be fitted either with ball or roller cages. With many years of experience RSD-bearings are the world-wide standard in hightech applications requiring first class performances and quality with minimum cost.
STRUCTURE AND FEATURES
NOTES BY ORDERING
Depending on the construction, the linear bearing can be fitted with ball- or roller cages with alternately crossed rollers. The construction consists of two pairs linear bearings; one pair consists of two similar 90° V-groove rails, through-hardened and precision ground, fitted with a cage in-between. Crossed roller cages are used in highload and high-precision applications (note: good dust protection is in this case required). Cages fitted with balls are used in applications which require less capacity, low friction resistance, or where dust and dirt are likely to penetrate into the rails (balls are affected less by dust or dirt, due to a self-cleaning effect of the balls).
One set linear bearings RSD consists of: 4 pcs. rails (=2 pairs), 2 pcs. cages and 8 pcs. end screws. By ordering please specify the following: • Quantity and type of rails • Quantity, type and length of cages or max. stroke • Direction of movement (eg: horizontal, vertical or in-between) • Quantity and type of end screws or end pieces with or without wipers. (in case of GC and GC-A, only 4 pcs are needed) Example: To order one linear bearing set of 300 mm length, size 6 mm for a 120 mm long horizontal stroke in standard quality please specify. • 4 pcs. rails RSD-6300 • 2 pcs. roller cages R6x20AA • 8 pcs. end screws GA-6
Rails are equipped with countersunk attachment holes, bored according to a standard configuration. Threaded holes in ends for fixing end pieces and wipers. For the attachment of the rails, special screws type GD can be ordered separately. (see page 35) On request we supply linear bearings with roller size ø 18 mm and ø 24 mm.
