Abstract

The invention relates to a bearing race (3) for a rolling bearing having a raceway (14; 15) for at least one roller (13) comprising a roller end face (21) having a first curvature and implemented as a partial sphere wherein the bearing race comprises a lip (31) disposed at the end face of the roller (13) for deflecting axial forces and having a lip surface (32) facing the roller end face wherein the lip surface (32) comprises a spherical lip surface segment (33) having a second curvature wherein the first and the second curvature are selected in order to obtain a first gap dimension (d) between the spherical roller end face (21) and the spherical lip surface segment (33) and wherein the lip surface (32) additionally comprises an opening lip surface segment (34) having a curvature less than the second curvature for a greater gap dimension (d) between the roller end face (21) and the opening lip surface segment (34).
