Abstract

A rolling bearing (1) for an exhaust gas turbocharger, including an outer race (2) and an inner race (3), between which there roll rolling bodies (4) guided by a cage (7). The cage (7) is then guided with a cage guiding surface (9) on a raceway (10) of the outer race (2) and is equipped with openings (11) which connect the cage guiding surface (9) with that side of the cage (7) oriented toward the inner race (3), in order to guide lubricant thrown off through the inner race (3) between the cage guiding surface (9) and the raceway (10). In order to now improve a lubricant supply to the cage guide, the cage (7) is provided, on the side oriented toward the inner race (3), with at least one groove (12) into which each of the openings (11) opens.
