Shaft Collars

Shaft Collars

Hold and position components on a shaft. Collars can also serve as mechanical stops and stroke limiters.

Shaft Connectors

Shaft Connectors

Couplings, universal joints, and flexible shafts connect two shafts together and transfer torque from one to the other.

Machinable Shaft Ends

One side is unfinished for milling custom pulleys, threaded hubs, sprockets, collars, knobs, sensor targets, or just about anything imaginable; the other side is a one-piece clamping coupling for mounting whatever you’ve created to your shaft.

Lead Screw Collars

Lead Screw Collars

Install these threaded collars on a lead screw to separate and position components, or use them as an end stop to limit travel.
