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 machinable bore have a large hub diameter so you can machine them to fit your shaft.
Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear's teeth increases its wear resistance.
