"Drive with Axle and Hub
If you wish to drive this wheel with an Axle and Hub, you can pick your hub by fitting any of the
AndyMark hubs (except the Small DD Globe Hub) to this wheel. Hubs are NOT included in the price of the wheel. If this is your choice, then no bearing is needed. To install a hub onto a 6" Mecanum Wheel, use
Hardware Kit 8."
