Taper-Lock Bushing-Bore V-Belt Drive Pulleys

Mount these drive pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft. These pulleys transfer force from the shaft to a V-belt in a power transmission system, and also help with misalignment. Made of cast iron, these pulleys are durable and resist wear.

Depending on the taper-lock bushing you choose, the same drive pulley can be used with different shaft diameters.
