Abstract
An axial roller bearing, in particular an axial needle bearing, having a first annular bearing disk and a second annular bearing disk that are each made of a thin-walled sheet steel and are arranged at a distance from one another on a common center axis, and a plurality of rolling elements, arranged next to one another, that roll between the axial inner sides—implemented as races—of the two bearing disks and that are held at uniform distances from one another by a bearing cage. The bearing disks are implemented as disk springs that deflect as a function of load and have races positioned at an angle, and are arranged relative to one another such that the rolling elements have low-friction point contact in the unloaded state of the axial roller bearing and only have load-bearing line contact with the races in the fully loaded state.
