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.
For tight spots, choose a pulley without a hub.

MXL Series Lightweight Timing Belt Pulleys
Made from polycarbonate, these pulleys are useful in applications with weight constraints. All are MXL series (miniature extra light) and have trapezoidal teeth. The teeth match up with the grooves along the inside diameter of a timing belt in order to move components forward or backward. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

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.
