1TB Split Taper Bushed Pulleys
1TB series pulleys are manufactured for A, AX, AA, 4L, B, BX, BB, and 5L v-belts and range 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. The majority of our 1TB 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.1TB Style Pulley Size Chart
