Abstract: An annular element for a rolling bearing comprises a cylindrical surface around the circumference of which a groove, the radial and axial depth of which are variable around the circumference, is formed. The cylindrical surface is suitable for being over-molded with a plastics material to form a body which is fixed firmly for rotation with the annular element and has a plastics projection complementary with the groove. The projection can cooperate with the groove to prevent relative rotation between the annular element and the body.

Abstract: Rolling contact bearing (1) for an electric motor presenting an inner race (2) which revolves around a rotation axis (A) and which is suitable for being mounted on a drive shaft of the motor itself, an outer race (3) which is fixed coaxial to the inner race (2), a number of revolving elements (4) which are interposed between the two races (2, 3) and at least one sealing element (8), which is mounted onto one side of the rolling contact bearing (1), and which is integral to the fixed race (3) so that it at least partially closes a gap between the two races (2, 3); a protective shield (10) which is mounted on the same side as the sealing element (8) and which is integral to the revolving race (2), and which presents a first annular section (10) which projects towards the inside of the gap (L) and which radially overlaps the sealing element (8) in order to partially shield the sealing element (8) itself.

Abstract: A sealing assembly for two mechanical members connected for relative rotation; a first mechanical member is fitted integrally with a substantially rigid shield, from which projects radially an annular sealing member having, on a respective first annular face, a first and a second axial sealing lip, both cooperating in sliding manner with a sealing surface of a second mechanical member; when the first annular face of the annular sealing member is subjected to a pressure substantially equal to the pressure on a second annular face, opposite the first, of the annular sealing member, only the first lip cooperates in sliding manner with the sealing surface, and the second lip mates, with no interference, with the sealing surface to permit fluid passage; conversely, when the first annular face is subjected to a pressure significantly lower than the pressure on the opposite second annular face, the annular sealing member is deformed elastically so that the second lip also cooperates in sliding manner with the sealin
