1. A rolling bearing assembly comprising:
an inner ring and an outer ring that are coaxial about an axis of rotation and between which rolling elements are arranged,
an annular metal rolling bearing cage centered about the axis of rotation and arranged radially between the inner ring and the outer ring, the annular cage having an outer annular face facing the outer ring and an inner annular face facing the inner ring, and
at least one insert comprising at least one tubular portion engaged in a recess of the annular cage and receiving one of the rolling elements, the tubular portion being connected at one radial end to a rim arranged in abutment against the inner annular face or the outer annular face of the annular cage,
wherein the at least one insert comprises a first latching means and the annular cage comprises a second latching means, the first latching means cooperating with the second latching means in order to hold the tubular portion of said insert housed in the annular cage, and
the first latching means of the at least one insert comprises a collar projecting radially from the tubular portion of said at least one insert towards the outside with respect to the axis of the recess comprising said tubular portion of said at least one insert, and the second latching means comprises a first shoulder radially facing said projecting collar,
wherein the tubular portion of the at least one insert comprises an annular portion formed opposite the rim of said insert, the annular portion being able to be inserted without deformation into a second shoulder of the recess, the second shoulder opening onto the inner annular face or outer annular face on which the rim of the insert is applied;
wherein the first shoulder opens onto an annular face of the annular cage opposite the annular face in contact with the rim of the insert, the first shoulder being arranged between the annular portion and the rim.
