These are all of our 9 mm wide 5 mm pitch HTD synchronous timing belt offerings. All of these belts are a composite of flexible rubber with a fiberglass tensile member throughout. Synchronous timing belts, also known as a toothed belt or synchronous belt, are designed to eliminate slippage and keep any number of objects rotating at a constant rate. We offer genuine Gates brand belts, AndyMark branded belts, as well as lower-cost generic brand belts.
Parts are organized by the following scheme: (Tooth Count - Trade Number - AndyMark part number)

Compliant wheels are not intended for moving robots, but moving objects. Compliant wheels give way to allow rigid objects to be manipulated easily. A line of multiple wheels on a driven hex axle creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors.
Different durometer ratings give each wheel unique characteristics. Green wheels (35A durometer) are the softest and most compliant around objects, maroon (45A), blue (50A), and black (60A) wheels are increasingly firm. The increased firmness also allows the latter wheels to carry a higher RPM rating. Check out the downloads tab for a chart showing wheels and their maximum RPM.

This new kit from Thriftybot allows you to drive 1.125" ID tubing in a number of ways. Using the Thrifty Metahub, plug into tubes and use your bearing bore of choice.
Kit includes all of the following -
- QTY 2 Aluminum Thrifty Metahubs - 24 Tooth HTD pulley that support the following configurations -
QTY 2 - 1" OD needle roller bearings for 3/4" OD tubes
QTY 2 - 1/2" hex bearings for hex shafts
QTY 2 - 3/8" ID bearings and a custom hex spacer. Run a 1/4-20 bolt thru your external material and then slip the roller tube in to connect the two hubs together.
Note that this kit provides enough parts to create a full roller with aluminum hubs on each end.
Thriftybot suggests this polycarbonate tubing from McMaster-Carr.
