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—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—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.

Plastic Bevel Gears

Large Gears | Small Gears |
Reduce speeds with these quiet-running, lightweight, and naturally rust resistant nylon gears. They're a better choice than metal gears for noise-sensitive areas and designs with weight constraints, but they're not as strong. Because they’re self-lubricating, these bevel gears are commonly used in food machinery. They should not, however, come in direct contact with food or chemicals that will come in contact with food.
A complete set consists of a large gear and a small gear, also known as a pinion (sold separately). For the gears to mesh correctly, they must have the same face width, pitch or module, and pressure angle.
Speed Ratio—The ratio by which shaft speed is reduced when transferring motion from the smaller to the larger gear. To increase shaft speed, transfer motion from the larger to the smaller gear. Changing shaft speed also changes torque: as speed decreases, torque increases. To achieve the speed ratio listed, match it across a set of compatible gears.
