    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.
    Steel—Steel gears have hard, strong, and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals.

    Internal Gears
    Image of Product. Front orientation. Internal Spur Gears. Metal Spur Gears.
    Save space without losing power. Insert a standard spur gear inside one of these gears for a compact assembly that smoothly transmits 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.
    Steel—Steel gears have strong and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals.
