These wheels are sold in unassembled kits. This wheel is an improved design over the regular 8" Mecanum Wheels.
For a mecanum drive system to work you must use two right and two left wheels.

This innovative design is currently patent pending.
With Axle and Hub: If the wheel is being driven directly by a rotating shaft (like one on the Toughbox), then use an AndyMark hub, like the 500 Key Hub to mount directly to the shaft. Also, some spacers and a 1/4-20 screw and a 1/4" washer to cap the end of the shaft will hold the hub (and wheel) onto the shaft.
If driven by a sprocket, these parts are needed:
- Flanged ball bearings with 1.125" od: AndyMark offers a 3/8" id version (am-0573), and a 1/2" id version (am-0030)
- One 250 Sprocket Spacer and one 550 Sprocket Spacer are needed to space the sprocket out away from the wheel, so the chain clears the edge of the wheel.
- A sprocket with a bolt hole circle of 1.875" diameter mounts to the wheels'' interior screws.
