A sealed rolling bearing comprising an outer race, an inner race, rolling elements through which the outer race and the inner race are supported so as to be rotatable relative to each other, wherein the outer race and the inner race define therebetween a bearing space having two open ends, and sealing devices each sealing one of the two open ends of the bearing space, wherein each of the sealing devices comprises a sealing member mounted on a radially inner surface of the outer race at one end of the outer race, and a slinger mounted on a radially outer surface of the inner race at one end of the inner race, wherein for each of the sealing devices: the sealing member comprises a cylindrical portion press-fitted on the radially inner surface of the outer race at the one end of the outer race, and an annular portion inwardly extending from an inner end of the cylindrical portion, and formed with only a first radial lip and a second radial lip being in elastic contact with the slinger and_which extend axially outwardly from an inner peripheral portion of the annular portion so as to be axially spaced from each other; the slinger comprises a cylindrical portion press-fitted on the radially outer surface of the inner race at the one end of the inner race, and an annular portion radially outwardly extending from an outer end of the cylindrical portion of the slinger; the cylindrical portion of the slinger has an outer periphery formed with a cylindrical seal slide-contact surface with which the first radial lip and the second radial lip are in elastic contact; and characterized in that the annular portion of the slinger comprises an inwardly bent portion, and a disk portion extending from an outer periphery of the inwardly bent portion, substantially parallel to the annular portion of the sealing member, wherein the disk portion is out of contact with the sealing member, thereby defining a labyrinth gap between the disk portion and the annular portion of the sealing member. the sealing member comprises a cylindrical portion press-fitted on the radially inner surface of the outer race at the one end of the outer race, and an annular portion inwardly extending from an inner end of the cylindrical portion, and formed with only a first radial lip and a second radial lip being in elastic contact with the slinger and_which extend axially outwardly from an inner peripheral portion of the annular portion so as to be axially spaced from each other; the slinger comprises a cylindrical portion press-fitted on the radially outer surface of the inner race at the one end of the inner race, and an annular portion radially outwardly extending from an outer end of the cylindrical portion of the slinger; the cylindrical portion of the slinger has an outer periphery formed with a cylindrical seal slide-contact surface with which the first radial lip and the second radial lip are in elastic contact; and characterized in that the annular portion of the slinger comprises an inwardly bent portion, and a disk portion extending from an outer periphery of the inwardly bent portion, substantially parallel to the annular portion of the sealing member, wherein the disk portion is out of contact with the sealing member, thereby defining a labyrinth gap between the disk portion and the annular portion of the sealing member.
