Fiberglass reinforced nylon round belt drive pulleys. Our 3/8" pulleys are standard round idlers with low sidewalls/flanges. The 1/4" are cable pulleys with high sidewalls. All pulleys will work with belts thinner than the rated size. Click here for more info on our round belt pulleys. Some drive pulleys are not in stock, and may require a $150 mold setup fee or a large minimum order. Contact us for price and availability.
Standard drive shaft sizes are 3/8", 1/2", 3/4" and 1". 1/4" and 5/8" drive bores are available via bronze bushings which reduce the ID of our 3/8" and 3/4" drive bores.
