AT Series Timing Belt Pulleys

Made of aluminum, these pulleys have good corrosion resistance. 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. Choose pulleys that have a diameter to match your shaft.
