Tapered bushings provide a lower-cost, straightforward, and quick method of securing sprockets, pulleys, and couplings on standard metric and imperial shafts in a variety of frequent business tolerances and finishes. The tapered surfaces on the bearing pad and mating hub are pushed with each other by large-energy screws, enabling the break up bearing pad to shrink securely onto the shaft. Powerful clamping force permits substantial torque transfer without having the fretting troubles linked with a straightforward important actuation.
