38mm x 13mm Traction Wheel assembly - internal set screw

These are the big brother to the regular RW28x13 / RW2, for when you need more clearance and traction. It 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.
