BALL SCREW AND NUT CHARACTERISTICS DEFINED

INCH BALL SCREW AND NUT TECHNICAL DATA

These definitions/descriptions are for the Product Specifications listed on the ball screw pages. Additional technical information on the preceding pages are designed to help you in selecting a ball screw and nut Lead Accuracy Measured in inch/foot or µm/300mm. See page 94 for additional screw lead accuracy specifications. Starts The integral number of helical thread elements on the screw shaft. Ball Circle Diameter The diameter of the circle generated by the center of the bearing balls.

that is best for your application. For additional assistance please contact our Application Engineers at 800-321-7800.

0631-0200 SRT LEAD ACCURACY: ±0.004 in./ft. Single Start 0.631 Ball Circle Diameter 0.200 Lead 0.500 Root Diameter 0.125 Nominal Ball Diameter 0.82 Screw Weight (lbs./ft.)

Lead The distance the nut advances in one revolution (lead = pitch x number of starts). Root Diameter The diameter of the screw at the bottom of the thread groove.

Ball Nut Quantity Ball quantity and size are nominal and may vary per nut.

Nominal Ball Diameter The approximate diameter of the load carrying balls contained in the ball nut. Screw Weight/Mass Measured in lbs/ft for inch screws and in g/m for metric screws. Ball Nut Style Heading The style of nut is identified in the drawing heading, refer to page 94 for additional nut style description.

Ball Nut Threads/Materials All screws have an alloy steel right hand threaded nut and many sizes have an alloy steel left hand threaded and a stainless steel right hand threaded nut.

SBN Single Circuit Ball Nut PRODUCT SPECIFICATIONS

Load Capacity Measured in lbs. or N, this is the dynamic and static load rating of the nut. Torque To Raise A linearly scalable value measured by in.-lb./lb. or N.m/kN. This is the torque required to keep one pound or one kN of load in motion. Ball Nut Weight, Ball Nut, Flange and Wiper Kit Part Numbers Wiper Kits are available for most nuts.

INCH BALL SCREW ASSEMBLIES TECHNICAL DATA

PowerTrac™ modular assemblies are pre-engineered and feature an SRT ball screw, steel mounting flange with an SBN ball nut, one single and one double bearing EZZE-MOUNT™ support. One end of the mounted screw is provided with a drive shaft and keyway for coupling the assembly to a drive mechanism.

BALL SCREW ASSEMBLIES

TWIN-LEAD BALL SCREW ASSEMBLIES

™

PRECISION BALL SCREW ASSEMBLIES

Twin-lead ball screws offer dual opposing motion using a single drive system. These one-piece high performance ball screws are made from high alloy steel that is black oxided for protection. Twin-lead ball screw assemblies can be assembled with Nook PowerTrac™ ball nuts, flanges and EZZE-MOUNT™ (see page 190 -192) bearing supports to form cost effective systems. Twinlead ball screws can be used in molding machines, packaging equipment, food processing machinery, robotics, material handling equipment, tire manufacturing and assembly applications. •

Lead accuracy of ±0.004"/foot is standard

Twin-Lead screws are stocked for immediate delivery without machined ends in the sizes and are highlighted in the chart below. To order a twin-lead cut to a custom length and/or with machined ends, select a size from the Twin-Lead Chart, determine OAL, LH and RH thread length, nut, flange and, if required, EZZE-MOUNT™ bearing support.
