A sealed rolling bearing includes slingers and seal members disposed between an inner ring and an outer ring, and sealing a rolling element installation area. The radially inner and outer portions of each slinger are bent axially inwardly such that a labyrinth portion is defined between the radially outer bent portion of the slinger and the radially inner surface of the outer ring, the labyrinth portion having a path length, in the axial direction of the bearing, longer than the material thickness of the slinger.
