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.

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.

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.
