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.
Corrosion-Resistant 18-8 Stainless Steel—Won't corrode from frequent washdowns and mild chemicals, including ammonia often found in cleaning solutions.
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.

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.

Metal Spur Gears
Gears
 |  |
20° Pressure Angle Round Bore | Gear with Round Bore and Set Screw |
20° Pressure Angle—The current industry standard, these 20° pressure angle spur gears have thicker, stronger teeth than 14½° pressure angle gears.
Steel—Steel gears have hard, strong, and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals.
Brass—Brass gears are easy to machine, so you can add your own mounting holes and make other alterations. They won't rust when exposed to water.

Gear Racks
 |  |
20° Pressure Angle—Rectangular | 20° Pressure Angle—Round |
These racks match with spur gears to convert rotary motion to linear motion. For components to mesh correctly, they must have the same pressure angle and pitch/module.
Steel—Steel gear racks have strong and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals.
Brass—Brass gear racks are easy to machine, so you can add your own mounting holes and make other alterations. They won't rust when exposed to water.

Save space without losing power. Insert a standard spur gear inside one of these gears for a compact assembly that smoothly transmits motion. Combine gears with different numbers of teeth to change speed and torque in your assembly. For components to mesh correctly, they must have the same pressure angle and pitch/module.
Steel—Steel gears have strong and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals.
