10B Split Taper Bushed Pulleys

10B Split Taper 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 Q2, R2, or U0 taper bushings, which we also stock. The majority of our ten-groove 10B split taper 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.
