H Bushings are designed for A-Section (4L and A) and B-Section (5L and B) v-belts and pulleys. Their solid flange and double-split barrel enhance concentricity and provide a strong grip on the shaft. Tightening the included cap screws causes the bushing to secure the shaft and pull into the pulley. These bushings feature a 3° taper and are made of steel, with keying for both the shaft and hub to aid in blind installations.
