Plain Bore |
Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.
Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.
Wear-Resistant Steel with Hardened Teeth—These sprockets have teeth that are hardened from the tip to the base so they withstand chain contact and wear evenly. That means fewer broken teeth and a longer lifespan than sprockets with unhardened or tip-hardened teeth. Steel is best for dry environments since moisture will cause it to rust.
Finished Bore—Mount these sprockets onto your shaft and secure with a set screw—no machining required.
Plain Bore—Plain bore sprockets give you options—machine a custom bore, weld, or press-fit them in place. They're sized to the minimum shaft diameter listed and are machinable up to the maximum.

Timing Belt Pulleys
 |
Bushing 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.
Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it. As you tighten the included set screws, the bushing grips the shaft and draws it into the pulley, creating a final hold that is more secure than with set screws alone.

High-Torque HTD Timing Belt Pulleys
 |
Bushing Bore |
 |
Curved teeth engage with the matching belt better than standard trapezoidal teeth, so these pulleys transmit about twice the torque. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP series.
Iron—Strong but best for dry environments since moisture will cause them to rust.
Corrosion-Resistant Stainless Steel—Stands up to wet environments and mild chemicals, such as the ammonia in cleaning solutions.
Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it. As you tighten the included set screws, the bushing grips the shaft and draws it into the pulley, creating a final hold that is more secure than with set screws alone.

Flush-Mount Screw-Clamp Bushings
 |  |
Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads. When you tighten the included clamping screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.

 |  |
A mounting flange prevents movement during tightening. These bushings are good for shock loads.
