    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.

    20° Pressure Angle

    Round Bore

    20° Pressure Angle—The current industry standard, these 20° pressure angle spur gears have thicker, stronger teeth than 14½° pressure angle gears.
    Stainless Steel—Stainless steel gears resist rust in damp and wet environments, so they're commonly used in food-processing plants and other areas with frequent cleaning.

    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.
    Stainless Steel—Stainless steel gear racks resist rust in damp and wet environments, so they're commonly used in food-processing plants and other areas with frequent cleaning.
    Hardened—Gear racks with hardened teeth have better wear resistance than racks with teeth that are not hardened.

    Precision High-Torque GT Timing Belt Pulleys

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

    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.

    Naturally rust resistant and lightweight, these plastic pulleys are ideal for machines that require frequent washdowns. Trapezoidal teeth, the original tooth profile, mesh with matching belts to transmit power without slipping.
    Plain Bore—Do it your way—machine the bore to your exact shaft size or add a set screw or keyway.
