Ultralightweight 6in Diameter Traction Wheel

thingiverse

This is a 6in Traction Wheel designed for use in FIRST Robotics Competitions on robot drive systems. It's meant to be used with a length of 1in wide traction tread material, just like any standard traction wheel from VexPro or Andymark, but at a fraction of the weight. These wheels fit the standard 1.875 in mounting hole pattern found on most FRC wheels. The axle hole can handle up to 2 standard 1.125" flanged bearings which mount flush to the surface of the wheel, or VexPro "VersaHubs". Tread can be attached with 8-32 screws and nuts using the included mounting holes (making it easy to change tread without removing the wheel from the robot). Don't use pop-rivets to attach tread to these wheels! These wheels have been proven to last for up to 2 district events (during the 2019 season) before needing replacement. Depending on the application, you might see some degradation of the edge of the wheel rim where the tread sits over time; this is normal and just a cosmetic issue. Wheels should be replaced if any damage is found in areas that directly support the tread or the mounting holes. Total weight using eSUN PLA+ material: ~0.434lbs per wheel (wheel only, no tread or hardware included).
