OG exemplary drawing
 
1. A bearing ring of a roller bearing, comprising:
an outer annular surface;
an inner annular surface;
two end surfaces;
an annular sealing disc connected to one of the two end surfaces;
fasteners, each including a shank and a head, which has an enlarged diameter with respect to the shank, and respective ones of the shanks extend through bores in one of the end surfaces and the sealing disc connected thereto;
wherein the outer annular surface has a cylindrical contour and the inner annular surface provides a raceway having a spherical contour, and a bore center axis of each said bore in one of the end surfaces and in the sealing disc has an engaged profile which converges towards the cylindrical contour while extending into the end surface; or
wherein the outer annular surface includes a spherical contour and the inner annular surface includes a cylindrical contour, and a bore center axis of each said bore in one of the end surfaces and in the sealing disc has an engaged profile which diverges from the cylindrical contour while extending into the end surface.
 
5. A self-aligning roller bearing, comprising: the bearing ring according to claim 1.
 
6. A bearing ring of a roller bearing, comprising:
an outer annular surface;
an inner annular surface;
two end surfaces;
a respective annular sealing disc connected to each of the two end surfaces;
fasteners, each including a shank and a head, which has an enlarged diameter with respect to the shank, and respective ones of the shanks extend through bores in each of the end surfaces and the respective sealing disc connected thereto;
wherein the outer annular surface has a cylindrical contour and the inner annular surface provides a raceway having a spherical contour, and a bore center axis of each said bore in one of the end surfaces and in the sealing disc has an engaged profile which converges towards the cylindrical contour while extending into the end surface; or
wherein the outer annular surface includes a spherical contour and the inner annular surface includes a cylindrical contour, and a bore center axis of each said bore in one of the end surfaces and in the sealing disc has an engaged profile which diverges from the cylindrical contour while extending into the end surface.
