"Despite the top-quality materials like corrosion-resistant steel and aluminum and due to the simplicity of the bearing which even took over the lateral guidance by its use as flange bearing, the estimated total costs of the construction are less than that of an equivalent mounting with roller bearings, which additionally required an extremely accurate alignment of the eight thrust roller units (consuming a lot of time ). ”
