Mill custom pulleys, threaded hubs, sprockets, collars, and sensor targets and mount them to shafts

8 products

U-Joints

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

18 products

Shear Couplings

Sever the connection between shafts when there's too much torque to protect parts from breaking

1 product

Bore Reducers

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

1 product

Shaft Collars

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

77 products

Torque Limiters

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

10 products

Clutches

Start and stop the transmission of power to machinery

9 products

Chain and Belt Torque Limiters
