Plastic 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 plastic, they run quieter than metal gears and have good corrosion and chemical resistance. They’re 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.
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.
