    Sprockets

    Image of Product. Finished Bore. Front orientation. Drive Sprockets. Sprockets, For Single Strand, Finished Bore.

    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.

    Metal Internal Spur Gears

    Save space without losing power. Insert a standard spur gear inside one of these gears for a compact assembly that smoothly transmits motion. These gears have teeth with a 20° pressure angle, the current industry standard. 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears.
    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.
    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.

    Metal Spur Gears

    Our strongest spur gears for transferring motion. They’re better than plastic gears for high-load, high-speed, and heavy duty applications. Combine a gear and rack to convert rotary motion into linear motion. To minimize your footprint, mount one or more standard gears inside of an internal gear.

    Plastic Spur Gears

    Made of plastic, these spur gears run more quietly than metal gears and have good corrosion and chemical resistance. However, they’re not as strong as metal gears, so they’re best for light duty applications. Combine a gear and rack to convert rotary motion into linear motion.

    20° Pressure Angle—The current industry standard, these 20° pressure angle spur gears have thicker, stronger teeth than 14½° pressure angle gears.
    14 1/2° Pressure Angle—A former industry standard, 14½° pressure angle gears are often found in older machinery.
    Acetal—Acetal gears absorb less water than nylon gears, so they’re less likely to swell.
    Nylon—Nylon gears are wear resistant, but will swell and weaken over time when wet.
