Professional Applications & Engineering Value
This 5/8-8 ACME lead screw is engineered to solve critical challenges in precision motion control systems, such as CNC machinery, linear actuators, and automated positioning equipment. The Black-Oxide 4140 alloy steel material, combined with hardening to Brinell 271 hardness, provides exceptional resistance to abrasion and deformation, minimizing maintenance downtime. The ACME thread type and Class 2C thread fit ensure efficient power transmission with low friction, while the ±0.009" per foot accuracy guarantees repeatable movements in industrial settings. Fully threaded and right-hand configured, it supports consistent force distribution across the 6-foot length, making it a reliable choice for high-duty cycles and long-term operational stability.
Specification Summary & Compliance
This lead screw adheres to Class 2C thread fit standards for precise thread engagement and features a 5/8"-8 ACME thread with right-hand direction. Manufactured in the inch system, it delivers a travel distance of 0.125" per turn with tight accuracy tolerances. The component is fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring it meets environmental safety requirements for industrial use.
