Claim 0:
1. A rolling-element bearing for a turbomachine, comprising:
an internal ring defining a first raceway having a first diameter,
an external ring defining a second raceway,
a plurality of rolling-elements disposed between the internal and external rings and adapted to roll on the first and second raceways,
wherein the bearing has at least one loop circuit for forced recirculation of lubricant, said loop circuit comprising a first recirculation circuit comprising at least one lubricant inlet located at the level of the second raceway and connected by at least one first duct created in the external ring to at least one lubricant outlet which opens onto a second recirculation circuit of the loop circuit, said second recirculation circuit comprising at least one second duct created in the internal ring,
wherein each of said at least one lubricant inlet of the first recirculation circuit forms an orifice opening onto the second raceway, the rolling-elements being able to roll over said orifice.
