    Plastic Sprockets

    Image of Product. Front orientation. Drive Sprockets. Plastic Sprockets.
    Quiet-running, lightweight, and naturally rust resistant. Choose these sprockets for noise-sensitive areas, designs with weight constraints, and machines that require frequent washdowns. Their teeth mesh with your roller chain to smoothly transmit power. All are made in the U.S.
    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.

    For Single Strand

    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.
    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.

    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.
    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.

    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.
    Corrosion-Resistant Aluminum—Won't rust in wet environments and one-third the weight of steel and iron. However, aluminum pulleys are not as strong as iron and steel.

    For 90° Shaft Angle

    With straight, conically shaped teeth and a 1:1 speed ratio, miter gears connect two shafts at an angle without changing shaft speed or torque. They're more efficient than spiral miter gears because they create less friction.
    For two gears to mesh correctly, they must have the same pressure angle, shaft angle, pitch/module, and number of teeth.
    1117 Carbon Steel—Carbon steel gears have hard, strong, and wear-resistant teeth. They’re best for heavy duty and high-torque applications, such as lifting equipment. However, these gears will rust when exposed to moisture or corrosive chemicals. Some gears have hardened teeth for additional wear resistance; gears with teeth that are not hardened can be hardened to fit your application.

    When precise synchronization is crucial, these pulleys minimize play (backlash). They’re often found in 3D printers, where accurate positioning is essential. Their curved teeth fit snugly with matching belts. Compared to pulleys with standard trapezoidal teeth, these pulleys transmit about three times more torque and run at higher speeds. All are compatible with Gates PowerGrip GT, 2GT, GT2, GT3, and GT4 series.

    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.
