Professional Applications & Engineering Value
This self-reversing lead screw assembly solves critical motion control challenges in industrial automation, CNC positioning, and material handling systems. The 1144 carbon steel lead screw with Rockwell C27 hardness provides exceptional resistance to deformation under continuous 150 lbs dynamic thrust loads, while the diamond thread form ensures smooth bidirectional movement with minimal maintenance. The aluminum square nut reduces overall mass without compromising durability, making it ideal for high-cycle applications requiring precise 1" travel distance per turn with ±0.005" accuracy. Engineered for demanding environments from -50° to 350° F, this system delivers reliable performance in packaging machinery, automated assembly lines, and precision measurement equipment.
Specification Summary & Compliance
Manufactured to inch system standards with Class 2A thread tolerances, this lead screw features diamond thread form with both right-hand and left-hand threading on a partially threaded 29½" length. The assembly delivers 17¾" travel length with precise ±0.005" per inch accuracy and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for international industrial applications.
