Ball bearing cage (4) consisting of a bead ring (7) and a substantially axial portion (8) fitted with claws (11) that define alveolus (9) for balls and joining on the bead (7), the substantially axial portion (8) stretching axially on one portion of the alveolus (9). The substantially axial portion (8) presents an external diameter inferior to the external diameter of the bead (7), the external diameter of the substantially axial portion being comprised between the primitive diameter of the cage reduced to half of the radial thickness of the diameter of the bead and the primitive diameter increased to half of the radial thickness of the bead. |
