Professional Applications & Engineering Value
This M8 metric ball screw is engineered to solve core challenges in precision motion control and linear actuation. The carbon steel screw, combined with the alloy steel flange nut, delivers a robust solution for applications requiring high dynamic thrust capacity (470 lbs) and minimal backlash (0.05mm), such as CNC positioning tables, automated assembly systems, and precision measuring equipment. The 2mm travel distance per turn and ±0.210mm accuracy provide the fine control necessary for high-repeatability tasks, while the rolled thread fabrication ensures a durable, cost-effective component suitable for continuous operation in industrial environments. Its right-hand thread and fully threaded design offer versatile integration into various mechanical drives.
Specification Summary & Compliance
This M8x2mm ball screw features a Metric Ball thread type with a 2mm pitch. Key dimensional specifications include a ball screw root diameter of 6.6mm and a length of 250mm. The flange ball nut has a diameter of 20mm, a length of 28mm, and a flange with mounting hole center-to-center distance of 30mm. The assembly is manufactured to provide high precision and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
