ABSTRACT:
In a sealing device for angular contact ball bearings comprises an outer race (20), a pair of inner adjacent half-races (30, 31) and two sets of balls (40, 41) interposed between the outer race (20) and the two inner half-races (30, 31), respectively. The sealing device is mounted to one (30) of the two inner half-races (30, 31) in an axially external position and comprises a body of resiliently yieldable material. The sealing device comprises a retaining lip (14) so shaped as to face a concave surface (22) fast with the outer race (20) and stop against said surface (22) to prevent the inner half-race (30) from coming off when not locked in its operation position yet.
