A wheel assembly for axles of industrial vehicles, which is intended for mounting on a stub axle spindle (2) having a threaded free end (4), comprising a hub (10) which can be coupled to a brake drum (12), an outer bearing (8) and an inner bearing (9) which are inserted into the central cavity of the hub in proximity to its longitudinal ends and are immobilized therein by respective stop members, a spacer ring (17) placed between the axle spindle (2) and the inner bearing (9), and an axle nut (15) screwed onto the free threaded end (4) of the spindle (2) in order to immobilize the outer bearing (8). The spacer ring (17) is separated from the hub (10) and is in contact with the inner race (9') of the inner bearing (9); the stop members consist of a first shaped ring (18) secured to the inner wall of the hub by one or more fastening dowels (25), and of a second shaped retaining ring (26) secured to the inner wall of the hub by a threaded coupling, in which both the said elements (18; 26) define a series of radial apertures (24; 30). These apertures allow inspection and lubrication of the respective bearings (9; 8) which are immobilized thereby. <IMAGE> |
