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.
