These 28mm diameter (almost 1-1/8") wheels are ideal for mini-sumo robotics, with internal set-screw mounting and 3mm axle hole


Description [Hide]

This high-performance wheel features a silicone rubber molded wheel on a lathe-machined aluminum hub. The hub is narrower than the standard version, as the set-screw hole has been removed from the collar (which was then removed), and moved to the main part of the hub, under the wheel itself.

This makes for a narrower wheel for tighter installations. We've even found we can place the gearmotor gearhead in the hub cavity itself for very tight installations. It's ideal for mini-sumo, like our 1st place finishing Strong Bad!!

Specifications:

  • Tire:
    • 28mm (1.1") diameter,
    • 13mm (0.5") wide
    • 20D durometer
  • Hub:

    • 3mm shaft hole

Secure it to your motor shaft with the included 4-40 hex grub/setscrew (requires 0.050 hex wrench, like our HexW050).
