The wheel bearing has wheel hub (22) and rollers (2, 12). The rolling elements (5,6) of roller (2) are rolled on inner ring (3) and outer ring (1) respectively. The rolling elements (15,16) of roller (12) are rolled on inner ring (13) and outer ring (11) respectively. The two inner rings are cohesively connected to one another and are fitted with intermediate ring if the outer rings are contacted with wheel hub in opposite axial direction. |
