Professional Applications & Engineering Value

This heavy-duty clamping collar is engineered specifically for ACME lead screw applications where precision motion control is critical. The Black Oxide 12L14 Carbon Steel construction provides excellent wear resistance while the ACME thread form (1 1/4"-5 right-hand) ensures optimal load distribution across thread flanks, reducing wear and maintaining positioning accuracy. The integrated socket head clamping screw system delivers uniform clamping force around the 2 1/2" OD circumference, preventing slip-page under high-torque conditions in CNC machinery, linear actuators, and industrial automation systems. This clamping collar solves common alignment and retention challenges in precision mechanical assemblies, offering engineers a reliable solution for maintaining lead screw concentricity and preventing axial movement.
