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

Plastic Spur Gears
Gears
 |
20° Pressure Angle |
20° Pressure Angle—The current industry standard, these 20° pressure angle spur gears have thicker, stronger teeth than 14½° pressure angle gears.
Acetal—Acetal gears absorb less water than nylon gears, so they’re less likely to swell.
Metal Spur Gears

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 |
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.
