These 28mm diameter (1-1/8") wheels are ideal for mini-sumo robotics. The wheel hubs are now anodized Black!
Newly re-designed and manufactured, these beautifully machined aluminum hubs come with a generously thick rubber tire for maximum traction (ideal for mini-sumo, like our 1st place finishing Strong Bad!).
The tire mounted on the hub measures in at 28mm (1.125in) diameter and overall width (including set-screw flange) of 17.03mm (0.67in) wide. The hub is drilled for a 3mm axle ideal for the GM12a-14a/18 series of gear motors! It's a nice, fat, beefy wheel ideal for small robots! Secure it to your motor shaft with the included 4-40 hex grub/setscrew (requires 0.050 hex wrench, like our HexW050).
Want to mount this wheel on a shaft other than 3mm? We've got a limited run of these hubs manufactured with a 2mm pilot hole, so it's easy for you to drill it out to exactly whatever size you require!
Update: The original rubber tires are no longer in stock or production, so the RW2 comes stock with the RW2-T silicon-rubber replacement.
Wheels are sold individually and include a hub, tire and grub screw.
Entire wheel assembly weighs 12 grams.
