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, while orange (40A), 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. 

Please note maroon wheels are only intended for use in FTC. If more powerful motors are used to drive it the spokes may fail.

The inside black portion of this wheel is made from molded polycarbonate plastic. The outer tread is TPU (Thermoplastic PolyUrethane). This robust but lightweight wheel provides good traction on carpet and soft tiles. Stealth wheels are the perfect drive wheel for smaller (<50 lb.) robots, or for intakes and other auxiliary robot mechanisms. These wheels are available in a variety of bores and durometers. 4 in. Stealth Wheels feature a 6 bolt pattern on a 1.875 in. bolt circle for mounting sprockets, hubs, and gears. Nub Bore Stealth Wheels feature a 4 bolt pattern on a 16 mm bolt circle found in most FIRST Tech Challenge building systems. The lower the durometer the softer the wheel is, this makes it wear away faster, but also makes it more grippy.

Product Usage:
Many thread locking materials are not compatible with polycarbonate and can eat away at the plastic. Be sure to check which adhesives are okay to use with this product.

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!

The Intake Kit can be used to create intake systems and is ideal for the FIRST Technical Challenge (FTC) and World Robotics Olympiad (WRO). Used with the Silicone Rubber Tubing #76410

Tired of hex clamp collars that cost an arm and a leg? Tired of stripping out the set screw on your clamp collar? Need to add a collar in an assembly and don't want to remove everything from your hex shaft?

Me too! I've ran into all of the above scenarios multiple times building multiple robots. These collars are the holy grail -

• split so they can easily be added or removed
• lightweight 6061 aluminum
• .5 oz (.031 lbs) for one hex collar
• uses two 8-32 socket head cap screws that require a 9/64" allen wrench
• $4.00 per collar, sold in 5 packs
• anodized black for awesomeness

General Dimensions:

• When clamped on 1/2 inch hex shaft - approx 1.2 inch outer diameter
• 0.40 inches wide
• STEP file CAD Model Available

Machine Key, steel. Used in 2.5" CIM Motor shafts. 

Specifications:

• Width: 2mm (0.078 inch)

• Weight: 0.0008 pounds

This collar clamp is a one-piece shaft collar with a 1/2 in. bore, 0.984 in. OD, and 0.236 in. width. The thin line design reduces weight and allows for use in confined spaces. It has the clamp style benefits of not marring the shaft, easy removability, and indefinite adjustability while commonly being used for guiding, spacing, stopping, mounting, and component alignment.

Specifications:

• Material: 2024 Aluminum
• Bore: 0.500 in.
• Outside Diameter: 0.984 in.
• Thickness: 0.236 in.
• Weight: 0.017 Pounds
