A non-corrosive, small particle resistant wheel axle-bearing assembly for a free wheeling hand carry device is provided which includes a wheel, an axle spindle and an annular bearing. In a preferred embodiment of the invention, the wheel includes a central bore, an inwardly facing-surface, and an outwardly facing surface. The inwardly facing surface includes a centrally disposed retainer between the wheel and the body of the device. The outwardly facing surface includes a cylindrical recess for receiving a thrust flange. The axle spindle is integral with the body of the free wheeling device and includes a plurality of longitudinal channels which terminate in slots on the device's body. The annular bearing has a flange at its outer end, a plurality of locking projections at its inner end, and an inner cylindrical wall defining a central bore and an outer bearing surface. In a preferred embodiment of the invention, the bearing includes a plurality of locking ribs which run the longitudinal length of the inner cylindrical wall between the two ends, extending beyond the inner end to form the plurality of locking projections. When assembled, the wheel, axle spindle and bearing share the same axial centerline. The locking ribs of the bearing nonrotatably engage the locking channels of the axle spindle, which is centrally disposed within the wheel bore, thereby providing a nonslipping, particle resistant bearing surface.
