High-Strength HTD Timing Belts


HTD (high torque drive) timing belts have a curved tooth shape that provides higher strength than trapezoidal teeth. Belts are neoprene with fiberglass reinforcement for quiet operation. The teeth are nylon coated to protect the wear surface and minimize friction.

High-Strength Ultra-Quiet Timing Belts


Also known as GT profile belts, belts with curved teeth minimize vibration and noise output. The teeth distribute pressure uniformly, so they wear evenly and last longer. Close engagement of the tooth and pulley offers more precise timing in heavy-load systems than trapezoidal teeth and HTD belts. Belts are neoprene, which is flexible and operates quietly. The fiberglass reinforcement on these belts add greater durability.
