About Sizing Belts

Belts are abrasion-resistant urethane, so they don’t create dust while they run. They have steel reinforcement, which has very high strength, low stretch, and excellent shock resistance.

T 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. Pulleys without a shaft diameter have a pilot bore, so you can customize them to your needs.

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. Pulleys without a shaft diameter have a pilot bore, so you can customize them to your needs.
