Abstract

In a race wire bearing comprising two undivided, concentrically disposed race rings having race wires which are disposed in facing grooves and on which rolling members roll, the first race ring having two race wires, a carrying or support wire receiving the main axial load and a retaining wire receiving only the disengaging tilting moment, and being formed at a place on its periphery with a filling orifice closed by a plug, the improvement comprising the filling orifice (7,16) being disposed as to interrupt only one race wire, the interrupted race wire being a retaining wire (6,18) and the plug (3) having a raceway (8) which replaces the retaining wire (6,18) missing at the filling orifice.
