Please note, these wheels are not intended for high speed use.
The new hubs have a square and a round portion matching the molded center of the new wheels. The center round portion of the wheels is machined after molding to provide a close tolerance fit to the round portion of the hub eliminating the wobble or slop found in many molded wheels. The square portion provides excellent torque transfer from the hub to the wheel and provides the room for two set screws placed 90degrees apart to secure the hub to a shaft.
Installation is quick and easy. Simply slide the hub onto the shaft and secure it in place with the set screws. Push the wheel onto the hub and lock it in place with the snap ring. The hub does not extend beyond the wheel so multiple wheels can be mounted tight against each other. The hubs and wheels can be removed and reused or reconfigured at any time as needed.
