10B QD Bushed Pulleys
10B series pulleys are manufactured for A, AX, AA, 4L, B, BX, BB, and 5L v-belts and range from 5.75" to 38.35" in diameter. Depending on the pulley size they are made to use with
SK, SF, E, F, or J QD bushings, which we also stock. The majority of our ten-groove 10B QD bushed pulleys are manufactured from a high-strength grade 35 cast iron, are phosphate-coated and painted for anti-corrosion, and all of them are balanced at the factory for smooth machinery operation. The main benefit of using a QD (quick detachable) pulley is that if the bushing (hub) breaks you don't have to replace the whole assembly, or if just the pulley gets warn out you the same principle applies. The other big benefit is that there is a wider range of bore options with QD pulleys than "fixed-bore" style.
