5B series pulleys are manufactured for A, AX, AA, 4L, B, BX, BB, and 5L v-belts, ranging from 7.35″ to 38.35″ in diameter. Depending on the pulley size, they are made to use with R1 taper bushings, which we also stock. Most of our five-groove 5B split taper bushed pulleys are manufactured from a high-strength grade 35 cast iron, are phosphate-coated, and are painted for anti-corrosion. All of them are balanced at the factory for smooth machinery operation.
