An axial rolling bearing consisting of at least one annular bearing disc which has a circumferential raceway arched in profile cross section, and consisting of a multiplicity of rolling elements formed as bearing needles or bearing rollers and arranged next to one another in a circular form, which roll on the raceway of the bearing disc and are kept at uniform distances from one another by a bearing cage. The arched raceway is formed having at least one circumferential groove-shaped depression at least in the region of one of the two ends of the rolling elements.
