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.

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.

Neoprene—Durable and weather resistant, but lose elasticity if exposed to oil and fuel. These belts are reinforced, so they're strong enough to transmit power without stretching. Plus, nylon-coated teeth minimize friction and protect the surface from wear.

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.

Cut-to-Length Timing Belts

Use these timing belts for linear applications or join the ends to create a custom belt. Their 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 a GT tooth profile.
