Plastic Miter Gears
Gears Sold Separately
Connect two shafts at a right angle without changing shaft speed or torque. Made of plastic, these gears run quieter than metal gears and have good corrosion and chemical resistance.
For two gears to mesh correctly, they must have the same pressure angle, pitch/module, and number of teeth.
Nylon gears are self-lubricating, so they’re often used in food machinery. However, they’re not approved for direct contact with food or chemicals that will come into contact with food.
Acetal gears absorb less moisture than nylon gears and are less prone to dimensional change. They’re best suited for use in light duty applications such as prototyping.
