Abstract
A bearing ring for a roller bearing includes a raceway for at least one roller that includes an at least partially spherically formed roller end surface having a first curvature. A flange for transferring axial forces extends from an end of the raceway and has a flange surface that faces towards the roller end surface. A spherical flange surface section having a second curvature is defined on the flange surface. The first curvature differs from the second curvature such that a first gap (d) exists between the spherically formed roller end surface and the spherical flange surface section. The flange surface also includes an opening flange surface section having a third curvature, which is less than the second curvature, such that a second gap (d) exists between the roller end side and the opening flange surface section. The second gap is larger than the first gap.
