QD bushed (a-b-section) 8-groove sheaves have eight grooves on the sheave that can accommodate many types of V-belts, including A, B, AX, BX, 4L, and 5L. They are flexible sheaves that offer a range of horsepower. The rating of power transmission of the belt drive is dependent on the type and number of belts, the wrap angle of the belt of the smallest pulley, and the pulleys' rotational speed.The V-belts
s are made of rubber
or synthetic rubber stocks to allow them high flexibility so that they can bend easily around the sheaves. The belts may also be covered with a stock material to provide them with reinforcement and protection. When the sheaves are worn out, the QD bushings allow for easy detachment and replacement. QD bushings also prolong the lifespan of the sheave by absorbing vibrations. QD bushed sheaves
(a-b-section) 8-groove can be used for severe duty applications such as shock and high starting loads. MRO Supply has a wide assortment of bushed sheaves in various styles and sizes. Filter by diameter, belt size and groove. For assistance, talk to our in-house experts today.
