The Solarbotics RW2 – Large Rubber Wheel features a beautifully machined aluminum hub with a generously thick rubber tire for maximum traction. A nice, fat, beefy wheel ideal for small robots! Secure it to your motor shaft with the included 4-40 hex set screw.

As this wheel is drilled for a 1/8″ axle, mounting it on our GM6/7 gear motor (a 2.1mm shaft) will not quite give you a true-running wheel. You will need to create a spacer sleeve to make up the difference to make it spin true. Splitting an 1/8″ brass tubing as a spacer does a great job of shimming it up while allowing the set-screw to still seat into the gear motor steel shaft.
