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.
