Professional Applications & Engineering Value

This precision ACME lead screw is engineered to solve critical challenges in motion control systems. The combination of 304 Stainless Steel and a Class 2C thread fit directly addresses the need for corrosion-resistant components that operate smoothly without seizing, even under continuous use. The ACME thread type is specifically chosen for its ability to handle high axial loads with minimal backlash, making it ideal for applications like CNC machinery, precision lifting equipment, and automated positioning tables. The guaranteed ±0.009" accuracy per foot ensures that systems maintain precise movement over the entire 6 ft length, reducing cumulative error and improving the overall reliability and repeatability of your industrial machinery. Its right-hand thread direction and single-start design provide predictable, straightforward integration into existing drive systems.

Specification Summary & Compliance

This lead screw adheres to the inch system of measurement with a 3/4"-5 ACME thread size and a Class 2C thread fit, which defines its manufacturing tolerance for a free-running assembly. It is fully threaded with a right-hand direction and a 1:1 speed ratio. The component is manufactured to deliver a travel distance of 0.2" per turn. Compliance with RoHS 3 (2015/863/EU) is confirmed, ensuring it is free from hazardous substances for use in various industrial and commercial applications.
