Positive Drive Pd™ belts give you the opportunity to design your drives for the speed, accuracy and dependability consistent with the best synchronous belt drives, all without the bulk, weight and added cost that is inherent in chain and gear power transmission systems. Our belts have precision-molded teeth to deliver the synchronized power you need. Because they are made of specially compounded rubber, reinforced with high-strength, stable fiberglass tensile cord members and have a long-wearing nylon facing, they are durable and provide a smooth, precise operation.
