12D QD Bushed Sheaves
12D series twelve-groove QD bushed sheaves are manufactured for D-series classic v-belts, as well as D banded belts, they range from 12.64" to 58.64" in diameter. Depending on the sheave size they are made to use an M, N, or P QD (quick detachable) bushings, which we also stock. The majority of our 12D 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.
