A conveyor pulley is a mechanical device similar to a conveyor roller that is used to change the direction of the belt in a conveyor system or to drive the belt or to put tension on the belt.

A conveyor pulley is more heavy-duty than a roller and is used at either end of a conveyor, or near the drive/motor. Choosing the right conveyor belt pulley can get tricky, which is where Heinrich Brothers Inc. can offer expert assistance.
