XL Series Corrosion-Resistant Timing Belt Pulleys
Pulleys are anodized aluminum, which is more corrosion resistant than steel. They are XL series (extra light) and have trapezoidal teeth. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

Metal Gears and Gear Racks—20° Pressure Angle
The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Compared to plastic gears and racks, they’re better for high-load, high-speed, and heavy duty applications. 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. To minimize your footprint, mount one or more standard gears inside of an internal gear.
For components to mesh correctly, they must have the same pressure angle and pitch/module.
Carbon steel components have hard, strong, and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals. They're best for high-torque machines, like lifting equipment, and heavy duty applications, such as rock crushing. Gears with teeth that are not hardened can be hardened to fit your application.

High-Power Metal Bevel Gears
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 of 2:1, 3:1, or 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.

Plastic Gears and Gear Racks—20° Pressure Angle
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.
Nylon gears can be operated without lubrication, so they’re commonly used in food-processing machines.
