Zusammenfassung:	A roller bearing having a first race, a second race, the races being coaxial and in relative rotation about a central axis, and a row of rollers. The first race including a circumferential groove disposed on a surface radially opposite the first bearing track, and at least one hole traversing the race substantially radially and opening out close to the first bearing track. The first race also provides a secondary groove extending in a substantially radial direction and connecting the circumferential groove to the hole. As such, it is possible for lubricant to be transferred from the circumferential groove to the hole via the secondary groove.
