Metal Gears and Gear Racks—14 1/2° Pressure Angle
A former industry standard, 14½° pressure angle gears are often found on older machinery. Made of carbon steel, they have high strength and are better than plastic gears and gear racks for high-load, high-speed, and heavy duty applications.
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.
For components to mesh correctly, they must have the same pressure angle and pitch.
Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear's teeth increases its wear resistance.

Gear Rod Stock
Machine your own gears to fit the exact face width and shaft diameter required. Rod stock has teeth with a 20° pressure angle, the current industry standard. 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Teeth are not hardened so you can machine and harden them to fit your application. Hardening a gear’s teeth increases its wear resistance. Also known as spur gear rod stock.
For gears to mesh correctly, they must have the same pressure angle and pitch.
