Professional Applications & Engineering Value

This ball screw nut is engineered from 17-4 PH Stainless Steel, offering superior corrosion resistance and strength for demanding industrial environments like CNC machinery, aerospace actuators, and medical equipment. Its 3/4"-4 ball thread and 0.5" travel per turn provide fast, precise linear motion, reducing cycle times and enhancing efficiency. The low backlash design minimizes positional errors, while the high dynamic thrust capacity of 600 lbs handles heavy loads without compromising accuracy. With a right-hand UN external thread (1 1/4"-16), it ensures easy integration and reliable performance in high-temperature applications up to 300° F, solving common issues of wear, misalignment, and environmental degradation in precision engineering systems.

Specification Summary & Compliance

This component features precise dimensions including a 2 15/16" length and 1 5/16" diameter, with threads conforming to UN standards (3/4"-4 ball thread and 1 1/4"-16 external thread). It maintains tight tolerances with a maximum backlash of 0.007" and is manufactured to ensure consistent performance. The product is RoHS 3 (2015/863/EU) compliant, adhering to environmental regulations for hazardous substance restrictions, and operates reliably within a broad temperature range from -65° to 300° F, meeting industry demands for durability and safety.
