Professional Applications & Engineering Value

This 1 1/2"-4 ACME left hand thread lead screw solves critical engineering challenges in heavy machinery and precision equipment. The ASTM B7 alloy steel construction provides exceptional strength-to-weight ratio, resisting wear in high-cycle applications while maintaining dimensional stability. The ACME thread profile delivers efficient power transmission with reduced friction compared to standard threads, making it ideal for motion control systems, industrial presses, and lifting equipment. The left-hand threading is particularly valuable in applications requiring opposite directional movement or where right-hand threads might loosen under vibration. With fully threaded design along its 6-foot length, engineers gain maximum flexibility in linear positioning systems while the Class 2G fit ensures consistent performance with commercial-grade nuts.

Specification Summary & Compliance

This lead screw features 1 1/2"-4 ACME left-hand threads with Class 2G thread fit per ANSI/ASME B1.5 standards, providing commercial accuracy for most industrial applications. The component meets ASTM A193/A193M specifications for high-temperature service and is manufactured from ASTM B7 alloy steel with documented 125,000 psi tensile strength and Rockwell C35 hardness. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while maintaining performance standards for global industrial markets.
