Offset hubs compensate for high parallel and angular misalignment

10 products

Other Products

Rigid Shaft Couplings

Join two shafts that are aligned and handle higher torque than flexible shaft couplings

26 products

Shaft Collars

Hold and position parts on a shaft, or limit shaft movement

56 products

U-Joints

Transfer torque between shafts at an angle; handle more torque and misalignment than flexible shafts

3 products

Bore Reducers

Adapt the bore of a component to a smaller size for mounting on a shaft

2 products

Torque Limiters

Keep torque at or below a set limit to control tension or braking or protect machinery from overload
