9 mm Wide 5 mm Pitch HTD Timing Belts - 160 Tooth

Each hub now has a "flower" pattern that fits and keys into our 42T 5 mm HTD Pulley, which means you are no longer constrained to our legacy 500EX Hex Hub for compatibility with this pulley. Every hub still maintains a closed-profile hole for maximum strength. Every shaft hub has been designed with bearing bosses on both sides that have been sized appropriately for the mating bearings that would pair with the bore through the hub, which means you can run each hub right against a bearing with no need for extra spacers. All of these hubs are also made from 7075-T6 aluminum, which is much stronger than the previously used 6061-T6, 6005, and 6105 alloys from our older designs. Where possible, the shoulder on shaft hubs was reduced to 7/8" in diameter for an easier fit with our molded plastic wheels, while still maintaining a precise 1.125" diameter boss for locating in wheels, sprockets, gears, and more. 

The holes are evenly spaced on a 1.875 in. circle and 0.201 inches in diameter. That's a perfect size for #10 bolts!

This 5M HTD aluminum pulley will allow teams to create belt reductions and drive mechanisms with a common 1/2" hex interface. We focused on robustness and tested them thoroughly during the 2024 season to ensure the flanges do not pop off during use.

- 18.5mm wide teeth allows for two 9mm belts or one 15mm wide belt

- Includes a small bump out to offset away from bearings.

Affordable and durable 2 inch squish wheels are now available. These wheels are commonly used by competitive robotics teams to move game pieces throughout their robot.

These wheels ship in packs of 10 for $3 per wheel and feature:

• 30A durometer TPE rubber material for maximum squishability
• .375 inch hex hole, intended to be stretched and used on 1/2 inch hex shafts or other larger OD tubes. Each wheel is 1/2 inch thick.
• Weight: .038 lbs per wheel
• STEP CAD file available

This is the "500EX Hex Hub" the bore is a 1/2" Hex Hole. It is a slightly different version of the 500 Hex Hub. It is manufactured differently, as it is extruded. Also, there is a 1.124" diameter boss on each side of the hub flange, providing a location for 1.125" bore flat sprockets. Are you having a hard time keeping your sprocket concentric with your hub? This hub is the trick.

This is the hub featured in the 2014 and 2015 Kit of Parts Drive Chassis and fits all AndyMark wheels.

This robust 5mm HTD 18mm 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 or crimps 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. 

This version of the pulley supports either two 9mm wide belts or one 15mm wide belt.

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.
