SDS Colson Wheel (Wheel Only)

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.

With custom hubs, this offering from SDS has competition-tested performance combined with seamless integration into the MK4 and MK4i Swerve Modules.

Colson Performa Wheels have been used extensively in BattleBots and FIRST Robotics Competitions, and are widely lauded as an intelligent choice for swerve. The durable co-injection molded construction of a thermoplastic elastomer tread permanently bonded to a polyolefin core helps ensure the wheel can withstand the rigors of robot competitions while being friendlier to non-carpeted surfaces and providing a more consistent performance throughout the life of the wheel compared to roughtop tread. 

The aluminum hub is secured to the bevel gear using three screws which captures the wheel. This setup provides a simplified replacement process for heavy use during competition season. 

Included Components in am- 5173:

• 3 - Black Oxide 10-32 1 in. Long Cap Screw (Similar to am-1056)
• 1 - Hub
• 1 - Colson Wheel (am-5171)

Specifications

• Brand: SDS

Tip-to-tip length is approximately 12.6 inches.

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.

Specifications

• Hole Pattern: Plates feature 0.20 in. Holes on a 1 in. Center to Center Spacing
• Material: 6061-T6 Aluminum
• Thickness: 0.125 in

Churro is a versatile extruded aluminum hex profile. The outside of this part is a 1/2 in. hex with small concave dimples which act as weight savings. There is an inside hole is sized at 0.2 in. in order to fit 1/4-20 thread forming screws. No tapping or threading is needed, as long as a thread forming screw is used. The outside hex size fits a 1/2 in. wrench or socket. 

The 3-foot churro, our most popular length and the best value on shipping, is available anodized in red, blue, purple, gold and black to dress up your robot. Anodized finish is hardy and doesn't flake off or add thickness like paint, but it is possible for a scratch to expose the bare metal beneath. Take basic precautions in your shop like watching for sharp tools or overtightening this churro in a vise.
