Timing Belt Pulleys


Finished 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.

Finished Bore—Mount these pulleys onto the shaft and secure with a set screw—no machining required.

Plastic Timing Belt Pulleys

Naturally rust resistant and lightweight, these plastic pulleys are ideal for machines that require frequent washdowns. Trapezoidal teeth, the original tooth profile, mesh with matching belts to transmit power without slipping.

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

Flush Hub—Ideal in tight spots where a raised hub would get in the way.
