M Type QD Bushings

M Type QD (Quick Detachable) bushings are precision-engineered components used to mount pulleys, sprockets, or sheaves onto shafts in power transmission systems. They feature a tapered, split design with a flange, allowing easy installation and removal without shaft damage. By tightening cap screws, the bushing securely grips the shaft, ensuring a tight, concentric fit. Made typically from steel or cast iron, M Type bushings accommodate larger bore sizes, offering high torque capacity and reliability in heavy-duty industrial applications.
