Professional Applications & Engineering Value
This 1 1/4"-4 ACME Lead Screw delivers critical precision in demanding motion control systems. Engineered from 1018 Carbon Steel, it provides the optimal balance of strength and machinability, resisting deformation under continuous operation. The fully threaded design and right-hand Acme thread ensure consistent force transmission in CNC machinery, industrial actuators, and automated positioning tables. Its Class 2C thread fit offers sufficient clearance for smooth operation with standard nuts, reducing binding risks. This component directly addresses engineering challenges requiring high tensile strength (64,000 psi) and ±0.009" per foot accuracy, making it ideal for applications where positional repeatability and long-term reliability are non-negotiable.
Specification Summary & Compliance
This precision Acme lead screw features a 1 1/4"-4 thread size with Class 2C thread fit per standard Acme threading specifications. It delivers a consistent travel distance of 0.25" per turn with an accuracy of ±0.009" per foot. Manufactured from 1018 Carbon Steel with a Brinell 126 hardness, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets.
