2B Split Taper Bushed Pulleys

2B 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 R1 taper bushings or Q1 taper bushings, which we also stock. The majority of our double 2B 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.
