How does a tapered bushing perform? The tapered part of the component is driven by way of a substantial-toughness screw with a mating hub, enabling the bushing to be securely fixed to the shaft. The power of the clamp can transmit high torque (rotational pressure). This style guarantees that a productively installed sprocket and pulley shaft are aligned with basic positioning.
