Self-aligning roller bearing having improved lubricant discharge, preferably for an aircraft turbojet engine speed reducer

A bearing (40) comprising:

• a rotating outer ring (44) having a spherical rolling track (52);
• first and second annular rows (54a, 54b) of rollers (42);
• and
• first and second rotary cages (56a, 56b) respectively associated with the first and second annular rows (54a, 54b) of rollers (42) for holding said rollers (42),
• wherein the first cage (56a) has an outer surface provided with at least one baffle (62) for discharging lubricant to a first side (64a) of the bearing (40) in a first axial direction (60a) from the second cage (56b) to the first cage (56a), said baffle (62) extending in a second axial direction (60b) beyond the rollers (42) associated with the first cage (56a), the second axial direction (60b) being opposite the first axial direction (60a),
• wherein said baffle (62) extends in the second axial direction (60b) also beyond the first cage (56a), so as to cover a portion of the second cage (56b), and
• wherein said baffle (62) extends in the first axial direction (60a) to an end of the first cage (56a) located at a first side (64a) of the bearing (40).
