    Plastic Spur Gear Racks

    Image of Product. Front orientation. Spur Gear Racks. Plastic Spur Gear Racks.
    Lightweight and resistant to corrosion and chemicals, these racks match with spur gears to convert rotary motion to linear motion in light duty applications.
    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 gear racks have thicker, stronger teeth than 14½° pressure angle gear racks.
    14 1/2° Pressure Angle—A former industry standard, 14½° pressure angle gear racks are often found in older machinery.
    Nylon—Nylon gear racks are wear resistant, but will swell and weaken over time when wet.
    Machined—Machined gear racks may be slightly bowed but will straighten out when installed.

    Plastic Spur Gears

    Made of plastic, these spur gears run more quietly than metal gears and have good corrosion and chemical resistance. However, they’re not as strong as metal gears, so they’re best for light duty applications. Combine a gear and rack to convert rotary motion into linear 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.

    20° Pressure Angle—The current industry standard, these 20° pressure angle spur gears have thicker, stronger teeth than 14½° pressure angle gears.
    14 1/2° Pressure Angle—A former industry standard, 14½° pressure angle gears are often found in older machinery.
    Nylon—Nylon gears are wear resistant, but will swell and weaken over time when wet.
    Plain Bore—Gears with a plain bore have a large hub diameter so you can machine them to fit your shaft.
