Abstract
A thrust ring, in particular an axial bearing thrust ring, for forming a running surface for rolling elements, for use in bearing systems for universal joints of cardan shafts. The ring has a first planar end side and a second end side, having two surface regions on the second end side which have been machined symmetrically with respect to a first axis of symmetry S of the thrust ring, and also in terms of its profile in the circumferential direction as seen starting from the first axis of symmetry, in the circumferential direction, to a further, second axis of symmetry S which runs at right angles to the first axis of symmetry S . Each of the surface regions can be described by a change in cross section of the thrust ring, which change comprises a reduction in the thickness dimensions describing the cross-sectional area in the region of the inner circumference and the outer circumference of the thrust ring, wherein the reduction in the thickness dimensions in the region of the inner circumference being less than in the region of the outer circumference.
