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.

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.

Metal Gears and Gear Racks—14 1/2° Pressure Angle
A former industry standard, 14½° pressure angle gears are often found on older machinery. Made of carbon steel, they have high strength and are better than plastic gears and gear racks for high-load, high-speed, and heavy duty applications.
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.
Gears with hardened teeth are more wear resistant than gears with teeth that are not hardened. Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear's teeth increases its wear resistance.

Plastic Miter Gears
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.
