8V Twelve-Groove QD Bushed Sheaves

8V series twelve-groove QD (quick detachable) bushed sheaves are manufactured for 8V belts and 8V banded belts. They range from 12.50" to 53.00" in diameter. Depending on the sheave size they are made to use an M, N or P QD bushing, which we also stock. The majority of our twelve-groove 8V 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.
