Made-to-Order V-Belts

If none of our standard V-belts have the outer circumference you require, tell us what size you need and we'll make one for you. Made of chemical- and abrasion-resistant polyurethane rubber, they are often used in light to medium duty power-transmission and conveying applications.

To Order: Please specify outer circumference in 1/4" increments.
