Timing Belts

Keep your drive system in sync. Trapezoidal teeth mesh with matching pulleys to transmit power without slipping. With the original tooth profile, these timing belts handle enough torque and synchronization for most applications. If you need high torque or precise starts and stops, consider curved tooth profiles, such as GT and HTD belts.

High-Temperature Silicone Rubber—The best for extreme heat, silicone timing belts resist sterilizing temperatures that would degrade other rubber. All are reinforced with aramid for very high strength and low stretch.
