INCH TWIN-LEAD 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™ 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
• For a shorter unthreaded center section, contact Nook Industries customer service 800-321-7800

Twin-Lead screws are stocked for immediate delivery without machined ends in the following sizes:
0375-0125, 0631-0200, 1000-0250, 1150-0200, 1250-0200, 1500-0250, 1550-1000

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. Consult the Twin-Lead Reference Number System in the Twin-Lead Assembly PDF above to complete your part number.
