4D Series Cast Iron QD Bushing Sheaves Pulley for "D" Belts
4D series four-groove QD bushed sheaves are manufactured for D-series classic v-belts and D-banded belts; they range from 12.64" to 58.64" in diameter. Depending on the sheave size, they are made to use an F, J, or M QD (quick detachable) bushings, which we also stock. Most of our 4D 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.
