Taper Lock Bushes
Standard Taper Lock bushes are designed for fastening pulleys, wheels, shaft couplings and other components to shafts. They are produced in standard series and dimensions from gray cast iron (for technological reasons, some sizes from steel).
Taper Lock bushes have a conical outer surface and a cylindrical inner bore with H7 tolerance including a standardized keyway (for technological reasons, some sizes with a reduced keyway). Once fixed, the component is capable of transmitting torque while being secured against axial displacement.
Bushes Fields of Use
Taper Lock bushes are used in a variety of industrial applications.
They are used to fix standard and non-standard V-belt, timing and flat pulleys, sprockets, TB hubs, shaft couplings and other components.
