Timing Belt Pulleys

Finished Bore

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.

Steel—Strong but best for dry environments since moisture will cause them to rust.

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

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