The ball bearing cage has a front face with retaining cavities (9) for a row of balls and a rear face comprising an annular body (10) with crenellations (10a) which ensure the relative positioning with a second cage of the same type fitted into the cage. The bottom of each crenellation is extended in the direction of the front face by teeth (11) separating the cavities. The teeth flanks have spherical bearing surfaces directed towards the center of the adjacent cavity. The front face comprises a fastening crown (8) connecting the teeth peripheral ends. |
