Made from carbon steel with spiral teeth, these gears handle heavier loads at higher speeds than bevel gears with straight teeth because their teeth stay in contact longer. Their teeth engage gradually, which reduces vibration and noise, and they’re hardened for extra wear resistance. Use these gears to transmit motion at a right angle while changing shaft speed and torque. They reduce speeds at ratios between 1.5:1 and 4:1. Customize their machinable bore to fit them on a variety of shafts. They’re also known as spiral bevel gears.

A complete set consists of a gear and pinion (sold separately). The gear is larger than the pinion, but for them to mesh correctly, they must have the same pressure angle, module, and face width.

Speed ratio is the ratio by which shaft speed is reduced when transferring motion from pinion to gear. To increase shaft speed, transfer motion from gear to pinion. Changing shaft speed also changes torque: as speed decreases, torque increases.

The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. 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/module.

Acetal gears are best suited for use in light duty machines or for prototyping. Gears with a clamping bore secure to shafts with a clamping screw. They’re easily removed or adjusted without marring your shaft.

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.

Reduce speeds where noise, corrosion, and frequent lubrication are a concern. Compared to metal gears, these nylon gears run more quietly, won't rust, and don't need to be lubricated. 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 gear and pinion (sold separately). For a gear and pinion to mesh correctly, they must have the same pressure angle, module, and face width. Plastic pinions can also be mated with metal gears, and plastic gears with metal pinions.

Speed ratio is the ratio by which shaft speed is reduced when transferring motion from pinion to gear. To increase shaft speed, transfer motion from gear to pinion. Changing shaft speed also changes torque: as speed decreases, torque increases.
