    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.
    Iron—Strong but best for dry environments since moisture will cause them to rust.
    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.
    Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it. As you tighten the included set screws, the bushing grips the shaft and draws it into the pulley, creating a final hold that is more secure than with set screws alone.

    Worm and

    Gear Sold

    Separately

    Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle. They transmit motion from worm to gear and cannot be reversed. For gears and worms to mesh correctly, they must have the same pressure angle, pitch/module, number of thread starts, and thread direction. These worms are compatible with plastic worm gears.

    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.

    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.
