Taper Lock Bushes

Taper Lock Bushes are standard conical bushes used as a locking mechanism for fixing pulleys, wheels, shaft couplings and other components to drive shafts.

The bushes have a conical outer surface and a cylindrical inner bore with H7 tolerance including a standardized keyway. Once fixed, the component is capable of transmitting torque while being secured against axial displacement.
