These pulleys are mounted using a tapered locking bushing to hold tightly to the shaft without wobble. These pulleys transfer force from the shaft to the V-belts in the power transmission system and also help solve misalignment problems. These pulleys are made of cast iron, which is durable and wear-resistant. Depending on the tapered locking bushing you choose, phase.
The same pulleys can be used for different shaft diameter.
