Metal Gear Rack - 20 Degree Pressure Angle

Manufacturer part: 2485N203

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.Carbon steel components have hard, strong, and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals. They're best for high-torque machines, like lifting equipment, and heavy duty applications, such as rock crushing.Gears with teeth that are not hardened can be hardened to fit your application.Spacers (sold separately) work with our metric gear racks to take the measuring and guesswork out of installing two racks end-to-end, so your gear rolls smoothly from one rack to the next. With the first rack fastened in place, roughly position the second rack. Place the teeth of the spacer into the teeth of the gear racks like a puzzle piece, and then adjust the second rack until all of the teeth fit together cleanly. Not for use with inch size gear racks.
