Rolling bearing with guiding flange for cage

A rolling bearing comprising:

• a first ring,
• a second ring,
• at least one row of radial rolling elements arranged between axial raceways provided on the rings,
• at least one row of axial rolling elements arranged between radial raceways provided on the rings, the second ring comprising a protruding nose engaged into an annular groove of the first ring and provided with the axial raceway and with the radial raceway of the second ring, and
• at least one cage for maintaining the row of axial rolling elements and at least one flange for guiding and maintaining the cage in radial direction,
• wherein the flange axially abuts against a flat surface of the second ring,
• wherein a plurality of fixing screws secure the flange to the second ring, the fixing screws extending axially through the flange,
