2B QD Bushed Sheaves Pulleys
2B series pulleys(QD Bushed Sheaves) are manufactured for 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 made to use with SH, SDS, SK, or SF QD bushings, which we also stock. Most of our two-groove 2B QD bushed pulleys 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. 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, or 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.
