3TC Split Taper Bushed Sheaves
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. The majority of our 3TC sheaves 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.
