<p>The method involves radially setting an inner ring (1), an outer ring (2) and a hollow cylindrical ring above one another. Diameter of the outer ring or the hollow cylindrical ring is changed at a respective outer ring edge (6) or hollow cylindrical axial edges. A thin intermediate layer (3) or an intermediate layer is inserted, while setting the rings above one another. The intermediate layer is removed after changing the diameter. The intermediate layer is made of metal, plastic or paper. The inner ring exhibits a shape of an equatorial spherical zone on an outer surface (8).</p> |
