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.

Abrasion-Resistant Urethane Rubber—Won’t break down or create dust while they run. Plus, they last longer than neoprene belts. Aramid or steel reinforcements provide very high strength and low stretch.

Timing Belt Pulleys


Plain Bore

Keep your drive system in sync. Trapezoidal teeth mesh with matching belts to synchronize motion. With the original tooth profile, these pulleys handle enough torque for most applications. If you need high torque or precise starts and stops, consider curved tooth profiles, such as GT and HTD pulleys.

Corrosion-Resistant Aluminum—Won't rust in wet environments and one-third the weight of steel and iron. However, aluminum pulleys are not as strong as iron and steel.

Plain Bore—Do it your way—machine the bore to your exact shaft size or add a set screw or keyway.
