The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Compared to plastic gears and racks, they’re better for high-load, high-speed, and heavy duty applications. Also known as spur gears.
Combine gears with different numbers of teeth to change speed and torque in your assembly. 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.
For components to mesh correctly, they must have the same pressure angle and pitch/module.
Brass gears and racks are easy to machine, so you can add your own mounting holes and make other alterations. They won't rust when exposed to water.
Gears with teeth that are not hardened can be hardened to fit your application.
Stainless steel gears and racks resist rust in damp and wet environments, so they're commonly used in food-processing plants and other areas with frequent cleaning.
