    Get pitch-perfect compatibility with these free-spinning pulleys. They mesh with belts that have curved GT-profile teeth, reducing vibration and wear. As they rotate on their bearings, these pulleys press up against belts to reduce slack and keep the system moving smoothly. All are compatible with GatesPowerGrip GT, 2GT, GT2, GT3, and GT4 series. Idler pulleys are often used with belt tensioners.
    Corrosion-Resistant Aluminum—Lightweight and resist rust in wet environments. Although aluminum pulleys are one-third the weight of iron pulleys, they aren't as strong.
    Without Teeth—These pulleys press against the smooth side of the belt instead of the toothed side to maintain tension.

    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—The current industry standard, these 20° pressure angle spur gears have thicker, stronger teeth than 14½° pressure angle gears.
    Steel—Steel gears have hard, strong, and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals.
    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.

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

    Gears Sold Separately

    Connect two shafts at a right angle without changing shaft speed or torque. Made of plastic, these gears run quieter than metal gears and have good corrosion and chemical resistance.
    For two gears to mesh correctly, they must have the same pressure angle, pitch/module, and number of teeth.
    Acetal—Acetal gears absorb less moisture than nylon gears and are less prone to dimensional change. They’re best suited for use in light duty applications such as prototyping.
