HTD belts have a curved tooth profile providing a positive drive between the belt teeth and the pulley grooves. The Belt is constructed of a flexible, durable chloroprene polymer which encapsulates the helically wound glass fibre tensile members. This gives the belt a high tensile strength and excellent fatigue life with virtually no stretch. The belts teeth are protected by a low friction woven nylon which protects the tooth surface from wear and aids in quiet efficient running. HTD belts have an operating temperature range of -25°C - +100°C. other sizes may also be available but may not be displayed please contact us if you require a size not displayed on our shop.
