6B QD Bushed Sheaves
6B QD Bushed Sheaves pulleys are working with A, AX, AA, 4L, B, BX, BB. And 5L v-belts, ranging from 3.75″ to 38.35″ in diameter. Depending on the pulley size, they are making with SD, SK, SF, or E QD bushings, which we also stock. Most of our six-groove 6B QD bushed pulleys are making from a high-strength grade 35 cast iron, with phosphate-coated, painted for anti-corrosion. We will balance the sheaves at the factory for smooth machinery operation. The main benefit of using a QD (quick detachable) pulley is that if the bushing (hub) breaks, you don’t have to replace the whole assembly. If just the pulley gets worn out, the same principle applies. The other significant benefit is that there is a broader range of bore options with QD pulleys than with the “fixed-bore” style.
