4TB Gripbelt Sheaves 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 working with P1 taper bushings or Q1 taper bushings, which we also stock. We produce most of our 4TB pulleys from a high-strength grade 35 cast iron. With phosphate-coated, and painted for anti-corrosion.
