Professional Applications & Engineering Value

This 1/2"-10 ACME lead screw is engineered for precision linear motion systems where accuracy and speed are critical. Manufactured from 1018 Carbon Steel, it provides excellent strength-to-weight ratio and resistance to deformation, addressing common issues like positional drift in CNC machinery, 3D printers, and automated positioning tables. The Acme thread type with Class 2C thread fit ensures minimal play and efficient power transmission, while the fully threaded, right-hand design allows for continuous travel without re-engagement delays. Its 2:1 speed ratio and ±0.009" per foot accuracy make it ideal for applications requiring fast, precise movements, such as material handling equipment, medical devices, and packaging machinery, where repeatability directly impacts throughput and product quality.

Specification Summary & Compliance

This ACME lead screw adheres to inch system standards with 1/2"-10 thread size and Class 2C thread fit for consistent dimensional accuracy. It features a travel distance per turn of 0.2" with ±0.009" per foot accuracy, 2 thread starts, and fully threaded configuration. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets international environmental and safety standards for hazardous substance restrictions.
