Abstract
A wheel hub that provides a wheel that is free-wheeling in both directions of turning and is constructed to provide low rolling resistance, greater load carrying capacity and is more reliable that earlier hubs. The hub includes separate bearing systems for supporting, respectively, radial loads as perpendicular to a road surface, and axial loads as are side loads directed into the hub. The separate bearing systems include a pair of radial bearings for supporting radial loads, with each radial bearing of the pair mounted at each hub end to receive an axle fitted therethrough, and a pair of thrust bearings for supporting axial loads, with each thrust bearing of the pair mounted at a hub end, between the radial bearings outer surfaces and an axle mounting to a frame.
