description The invention concerns an axial roller bearing (1), in particular an axial needle bearing, consisting essentially of a first annular bearing disk (2) and a second annular bearing disk (3) that are each made of a thin-walled sheet steel and are arranged at a distance from one another on a common center axis (AM), and of a plurality of rolling elements (4) arranged next to one another that roll between the axial inner sides-implemented as races (5, 6)-of the two bearing disks (2, 3) and that are held at uniform distances from one another by a bearing cage (7). According to the invention, the bearing disks (2, 3) of the axial roller bearing (1) are implemented as disk springs that deflect as a function of load and have races (5, 6) positioned at an angle, and are arranged relative to one another such that the rolling elements (4) have low-friction point contact in the unloaded state of the axial roller bearing (1) and only have load-bearing line contact with the races (5, 6) in the fully loaded state of the axial roller bearing (1).
