Patent ID: 8899839

Claim:
A bearing ring for a roller bearing having a raceway for at least one roller that includes an at least partially spherically formed roller end surface having a first curvature, the bearing ring comprising: a flange disposed on an end-side of the roller for transferring axial forces, the flange having a flange surface facing towards the roller end surface, a spherical flange surface section having a second curvature being defined on the flange surface, wherein the first and the second curvature differ such that a first gap dimension (d 1 ) exists between the spherically formed roller end surface and the spherical flange surface section, and the flange surface also has an opening flange surface section having a third curvature, which is less than the second curvature, such that a second gap dimension (d 2 ) exists between the roller end side and the opening flange surface section, the second gap dimension (d 2 ) being larger than the first gap dimension (d 1 ).
