12C QD Bushed Sheaves

12C series twelve-groove QD bushed sheaves are manufactured for C, CX, banded belts, and CC v-belts, they range from 9.40" to 50.40" in diameter. Depending on the sheave size they are made to use either a J or M QD (quick detachable) bushings, which we also stock. The majority of our 12C QD 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.
