24 Tooth HTD Pulley 1/2" Hex Bore

This item can only be purchased in multiples of 8

These solid polyethylene (PE) closed cell foam noodles are great for building bumpers for the FIRST® Robotics Competition.

This foam outperformed all other tested options when paired with a backing of Soft Tiles. 

A rough estimation is that about 6-8 pool noodles are used for 1 set of bumpers depending on robot size. Noodles are required to be purchased in multiples of 8. Read the robot rules to ensure you understand how to create legal bumpers based on this year's rules.

This retainer clip is used to hold objects (such as gears) in place on shafts. 

Example: This product can be used to hold a gear onto a CIM motor shaft. 

Specification: 

• Material: Steel
• Inner Diameter: 8mm
• Outer Diameter: 15mm
• Weight: Less than 0.001 lbs

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!

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.
