An anti-friction bearing, including a bearing ring (2), a bearing cage (5) for receiving at least one rolling body (4), a power supply unit (8) which is configured as a claw pole generator, wherein the claw pole generator (8) includes a first claw ring (10) with a sequence of first claws (11) and a second claw ring (12) which is offset in the circumferential direction of the bearing ring (2) and has a sequence of second claws, wherein the two claw rings (10, 12) surround an induction coil (9) encircling in the circumferential direction of the bearing ring (2), wherein the claws (11) of the two claw rings (10, 12) form, with a sequence of magnetic poles (14) encircling in the circumferential direction, magnetic circuits which surround the induction coil (9). The object of providing improved utilization of the installation space for receiving the claw pole generator for, in particular, two-row anti-friction bearings, specifically for self-aligning roller bearings, is solved according to the invention by virtue of the fact that the magnetic poles (14) are arranged on the bearing cage (5).
