Shaft Collars and Couplings

Rigid Shaft Couplings

Good for high-torque applications, rigid shaft couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.

Flexible Shaft Couplings

Connect two shafts with up to 15° of misalignment. Flexible shaft couplings perform better than U-joints and flexible shafts in high-speed, low-torque applications. They're also better than U-joints for applications requiring precise movement and directional changes.

U-Joints

Compared to flexible shafts, U-Joints handle much greater torque and misalignment but operate at lower speeds. Use them for distances up to 10".

Flexible Shafts

Able to handle any kind of misalignment, flexible shafts connect shafts up to 3 ft. apart. They snake around curves and obstructions to transmit rotary motion along any path.

Shaft Adapters

Shaft Adapters

Convert your shaft to a larger or smaller size while also extending it. One side has a coupling that connects to your shaft; the other is the converted shaft size.

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.

Torque-Limiting Shaft Couplings

Torque-Limiting Shaft Couplings

Also called slip clutches, these couplings slip when they exceed specific torque levels to protect motors and drivetrains and ensure safe operation.
