Professional Applications & Engineering Value
This Acme thread clamping collar solves critical positioning challenges in industrial automation and precision motion control systems. The Black Oxide 1215 Carbon Steel construction provides excellent wear resistance while the Brinell 167 hardness ensures dimensional stability under repeated clamping cycles. Engineered specifically for Acme lead screw applications, the 3/8"-16 Acme threads deliver superior load distribution compared to standard V-threads, reducing wear on both the collar and lead screw. The right-hand thread direction and clamp-on shaft mounting enable quick installation and adjustment without disassembling entire drive systems, making it ideal for CNC equipment, linear actuators, and positioning tables where maintenance downtime must be minimized.
Specification Summary & Compliance
This precision clamping collar features 3/8"-16 Acme threads with standard Class 2G tolerances for proper fit and function. The 7/8" outer diameter and 11/32" width provide optimal strength-to-size ratio. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global industrial applications. The included 6-32 socket head clamping screw follows standard inch measurement specifications for easy replacement and maintenance.
