Annular element for a rolling bearing

摘要

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-moulded 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.
