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.

Move belts forward and backward or stop and start them in precise positions, especially in areas where rust is a concern.

Keep high torque drive (HTD) timing belt systems running tightly with these idler pulleys. Made with built-in, free-spinning ball bearings, they're installed on shafts or belt tensioners to remove slack from timing belts.
