Shaft Couplings

Shaft Couplings

Connect two shafts to transfer rotary motion from one to the other

Machinable Shaft Ends

Machinable Shaft Ends

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

U-Joints

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