Shaft-Hub Locking Devices

Shaft-hub locking devices for internal applications fit between the component to be locked and the shaft.

Easy install unit slides into position and offers keyless shaft-hub lock that will simultaneously handle both high torque and thrust while increasing your shaft strength.

Shaft-hub locking devices frictionally clamp gears, pulleys, flywheels, and other components to a shaft without the need for threads or keys. Axial loads applied to the locking devices are translated into radial loads that clamp the gear, pulley, or other component to a shaft.
