HTD 3M timing pulley bar stock

3M timing pulley bar stock consists of aluminium bars with teeth for an HTD 3M belt with a 3 mm pitch. The rounded HTD tooth runs quietly and evenly, which is why the 3M profile is used in small, precise drives - in 3D printers, measuring devices, robotics and automation.

HTD 3M timing pulley bar stock - lightweight pulleys for small stepper motors

From the bar you can cut a pulley of exactly the width your design needs, including narrow or very wide ones. Aluminium is easy to cut and bore, and a light pulley does not load small stepper motors. After cutting, all you need to do is make the bore and fix it with a set screw or a bush.
