4 in. Performance Wheel with Nub Bore

The 4" Performance Wheel is a virtually indestructible wheel made out of solid 6061 aluminum. This competition-proven design has been used on FIRST Robotics Competition robots for many years, and is now available in a version friendly to FIRST Tech Challenge robots. This new iteration of the wheel has been designed to keep costs down, as it is made from a custom extrusion instead of being fully machined from billet in past versions of this wheel. This wheel can take anything an FRC or FTC robot can throw at it, and much more.

This wheel is designed to be driven by an AndyMark Nub and a 6 mm D shaft, using the Nub Bore. It also allows for other motion hardware that utilizes a 1.875" 6-hole bolt circle found in many AndyMark and competition robotics products. To mount one of these to the rear (flat) side, use a 250 Sprocket and Pulley Spacer. To mount one to the front, use a 550 Sprocket Spacer. This wheel does not include tread material, which is available separately to tailor this wheel's performance to your application.

Note: This wheel is designed to utilize a zip-tie to attach and tension the tread to the wheel. The method of attachment is similar to the previous version, except that the zip tie goes around the bolt instead of through the hole. A new guide on how to attach tread to this wheel is coming soon.
