64.2mm OD Sprockets | McMaster-Carr

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 Corrosion-Resistant Timing Belt Pulleys

Anodized aluminum has good corrosion resistance. Pulleys 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 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 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.
