4TB Gripbelt Sheaves with Split Taper Bushings

4TB series pulleys are manufactured for A, AX, AA, 4L, B, BX, BB, and 5L v-belts, ranging from 3.75" to 38.35" in diameter. Depending on the pulley size, they are made to use with P1 taper bushings or Q1 taper bushings, which we also stock. Most of our 4TB 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.
