Professional Applications & Engineering Value

This self-reversing lead screw and nut assembly delivers exceptional engineering value through its specialized diamond thread design and material selection. The 1144 carbon steel screw provides the necessary tensile strength (130,000 psi) and wear resistance for precision motion systems, while the aluminum square nut reduces overall weight without compromising performance. The partially threaded configuration with both right-hand and left-hand threading enables automatic reversal capabilities, eliminating the need for complex reversal mechanisms in automation equipment, packaging machinery, and precision positioning systems. This combination addresses critical industrial requirements for accurate travel distance control (1" per turn) within tight tolerances, making it ideal for applications where space constraints and precise linear motion are paramount.

Specification Summary & Compliance

The assembly features a 1" screw diameter with 23½" total length and 11¾" travel length, delivering precise linear motion through single-start diamond threads. Manufacturing adheres to inch system standards with ±0.005" per inch accuracy for travel distance. The system maintains RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current SVHC requirements, ensuring environmental responsibility and global regulatory acceptance for industrial applications.
