Professional Applications & Engineering Value

This ACME lead screw collar delivers critical performance in precision motion control systems where positioning accuracy and vibration resistance are paramount. The Black Oxide 12L14 Carbon Steel construction provides superior wear characteristics while the clamp-on design eliminates the need for shaft modifications, preserving lead screw integrity. The right-hand ACME threading (2 1/2"-3) ensures compatibility with standard lead screw configurations in CNC machinery, linear actuators, and industrial automation equipment. With Brinell 163 hardness, this collar maintains dimensional stability under continuous load cycles, preventing slippage in high-torque applications while the integrated socket head clamping screw simplifies maintenance procedures.
