Abstract

A sealed anti-friction bearing (1), including an annular sealing washer (11, 12) which seals a rolling-body chamber (7) in the axial direction, wherein the sealing washer (11, 12) has a fastening section (14) for connecting it fixedly to a bearing ring (2) of the anti-friction bearing (1) so as to rotate with it, and wherein the sealing washer (11, 12) is anchored with its fastening section (14) in a circumferential groove (22) of the bearing ring. According to the invention, it is provided that the fastening section (14) has a first clamping element in the form of a barb (19) and a second clamping element in the form of an annular bead (20), and that the barb (19) and the bead (20) enter into a non-positive connection with oppositely lying surfaces of the groove (22).
