3TC Series Cast Iron Sheaves with Split Taper Bushings for Use with All “C” Section Belts

3TC series three-groove sheaves are manufactured for C, CX, banded belts, and CC v-belts. They range from 7.40" to 24.40" in diameter. Depending on the sheave size, they are made to use Q1 taper bushings, which we also stock. Most of our 3TC sheaves 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.
