Abstract
A bearing for an angularly contacting bump stop, the washers of which consist of stamped sheet metal and have a surrounding geometry. The geometry of the bearing is such that, in every cutaway containing the geometrical axis of rotation of the bearing, the lower raceway forms a lower circle arc which defines a lower axial curvature center, the upper raceway forms an upper circle arc which defines an upper axial curvature center, the upper and lower curvature centers being located on an angular geometrical axis that forms with the geometrical axis of rotation an angle of obliquity of a value between 5° and 65°. Specifically, the lower circle arc has two ends defining an opening angle of a value greater than or equal to 80° and a tangent located in a lower plane perpendicular to the axis of rotation at a lower tangent point defining with the end of the nearest lower circle arc a portion of the lower circle arc having an opening angle greater than or equal to 10°.
