The cage was made from a metal and the surface of each socket (15) is designed to cooperate with one of the balls and is defined by an imaginary cylinder with an axis oriented radially and cut by the plane axially delimiting the cage on the side opposite the shoulder (16) so as to form an axial opening of the socket, the width of this opening being smaller than the diameter of the said imaginary cylinder.
