    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.

    14 1/2° Pressure Angle—A former industry standard, 14½° pressure angle gears are often found in older machinery.
    Steel—Steel gears have hard, strong, and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals.
    Plain Bore—Gears with a plain bore have a large hub diameter so you can machine them to fit your shaft.
    Hardened—Gears with hardened teeth have better wear resistance than gears with teeth that are not hardened.
