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. Lead accuracy of ±0.004"/foot is standard; For a shorter unthreaded center section, contact Nook Industries customer service at 800-321-7800.
Tests and tolerantes refer to the ball nut body displacement relative to the ball screw shaft. A pitch-to-pitch measurement may be carried out using a measuring ball by touching the ball track of a non-rotating ball screw shaft. For the measuring intervals, see table A.2.
Wiper kits are standard for all metric ball screw models and come pre-installed. The molded wiper is designed to keep large particulates from entering the ball nut. However for harsh environments, the use of boots or bellows to enclose the screw is recommended. Contact Rockford Ball Screw for further information on enclosures.
