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 both genuine Gates brand 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 shaft creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors. The wheels are sized for an interference fit and tend to stay in place on a shaft, though a shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing.
The hex bore versions of this wheel are undersized, and are intended to be an interference fit on their respective hex shafts. This interference fit allows for effective torque transfer from the hex shaft to the wheel, as well as allowing the wheel to remain in place along the shaft without the need for spacers or collar clamps:
Different durometer ratings give each wheel unique characteristics. Green wheels (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) 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 is a Heavy Duty Hex Bearing which outperforms our previous 1/2" Hex Bearings as it has a Heavy Duty Inner Race. This FR8ZZ-HexHD bearing, 1/2" hex bore, flanged, heavy duty inner race, shielded ball bearing, has an inner race that is thicker and stronger than our recent offering of a similar bearing (am-0279). This bearing has more material between the corners of the hex bore and the edge of the race making it stronger and much less likely to crack under high load.
This bearing is guaranteed to have a stronger, thicker race. 100% of these bearings have been quality checked for a smooth fit over 1/2" hex stock here at AndyMark. Many of our long-time customers will recognize this bearing, as it is the same version we sold back in 2008-2011, and we did not have any failures. Now, it is renamed and quality checked for your high load needs - including drive chassis with cantilevered wheels.

We are pleased to offer these new gussets that are suitable for 1" based building systems. These thoughtfully designed gussets are made from 1/8" thick 6061-T6 aluminum, which is a much stronger material than other 0.09" 5052 gussets. All of these framing gussets feature a 1" linear hole pattern, with holes suitable for either #10 screws or 3/16" rivets.
On all of the angle gussets, a generous radius was used on the inside corner for maximum strength. The various angle gussets, along with the quad and tee gusset are used together to create structures and sub-assemblies for your robot. Our bearing and Sport gussets are perfect building blocks to create a massive variety of mechanisms and assemblies to suit your needs.

This robust 5mm HTD 9mm wide aluminum pulley is a lightweight motion component thoughtfully designed specifically for FIRST Robotics Competition robots. It features a lightweight 2024 aluminum core, made from our 24 Tooth Aluminum Pulley Stock. Unlike other products on the market, this pulley uses super strong steel flanges that are formed onto the pulley body instead of using a traditional press fit for maximum flange retention and durability. This pulley has small bosses on each side that allow them to be installed against an FR8ZZ Round or FR8ZZ Hex bearing without rubbing on the outer races for smooth operation. Much like our 17 Tooth Magic Sprocket, this pulley is designed to fit perfectly inside a 2" x 1" aluminum box tube between two FR8ZZ Hex Bearings.
This version of the pulley supports one 9mm wide belt.
