CCI's Machined Drum Pulleys are manufactured from thick wall pipe or tubing, then machined on a lathe to form the crown and ensure minimum runout in operation.

    Our Machined Drum Pulleys are the heaviest in the business, featuring a 3/8" minimum end disc, or 3/4" thick integral hub and end discs, minimum 1/4" rims and 1/4" center plates. Because each pulley has been machined, the pulley is the thickest in the center where the load is the highest.

    Our Machined Drum Pulleys run more concentric than pulleys made by the "expansion" method. This ensures better belt tracking and less vibration transferred to the bearings.
