    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.

    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.
    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.

    14 1/2° Pressure

    Angle, Round Bore

    14 1/2° Pressure Angle—A former industry standard, 14½° pressure angle gears are often found in older machinery.
    Nylon—Nylon gears are wear resistant, but will swell and weaken over time when wet.
