3C Series Cast Iron QD Sheaves for “C” Belts

3C series three-groove QD bushed sheaves are manufactured for C, CX, banded belts, and CC v-belts; they range from 5.40" to 50.40" in diameter. Depending on the sheave size, they are made to use SD, SF, E, or F QD (quick detachable) bushings, which we also stock. Most of our 3C QD 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.
