RW2-2MM-2 - WHEEL RUBBER 28-31MM DIA 11MM WIDTH 2MM AXLE (2 pcs/pkg)

Brand

Piece Count

Model

These hubs are made 3.8mm (.15) wider than the RW2i (Inside) 
by making the setscrew hole on the aluminum rim outside the 
tire. It means you do not have to remove the tire from the hub 
to tighten it these tires come with a generously thick rubber 
tire for maximum traction. 
Ideal for minisumo like our 1st place finishing Strong Bad!

The tire mounted on the hub measures in at 31.2mm (1.23in) 
diameter and overall width of 13.2mm (0.52in) wide. 
The hub is drilled for a 2mm axle ideal for other motors and 
or custom axles! 
It's a nice fat beefy wheel ideal for small robots! 
Secure it to your motor shaft with the included 440 hex 
grub/setscrew. Requires 0.050 hex wrench like our HexW050. 

Although you can simply install the motor from the outside 
we designed it so you could be mounted internally to the hub. 
We've found that the internal cutout came back from manufacture 
a wee bit thick but a bit of filing on the edges of the GM12a 
lets it fit right in. By handfiling the edges down you can 
finetune the installation so the brass edges of the gearbox act 
as alignment bushing points that assist in keeping the wheel 
spinning true. Or use a Sherline lathe to remove 0.010 from the 
ID of the cutout!

Wheels each include a hub a tire and grub screw.

The entire wheel assembly weighs 12 grams.
