The bearing has a bearing region side equipped with a sealing joint comprising a flexible sealing element (2) associated with a rigid annular armature (1). The sealing element has an outer lip (4) and an inner lip (3), which are in rubbing contact on an outer surface (8b) and an inner surface (8a), respectively. The outer surface has a load-bearing capacity higher than 60 percent and a roughness higher than 0.5 micrometer. The inner surface has a load-bearing capacity and a roughness, which are strictly higher and lower than that of the outer surface, respectively. |
