    Metal Internal Spur Gears

    Image of Product. Front orientation. Internal Spur Gears. Metal Internal 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. These gears have teeth with a 20° pressure angle, the current industry standard. 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears.
    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.
