Support roller bearings are cylindrical roller bearings and can support very high radial or combined forces, depending on the design. The surface quality of the outer surface of the outer ring, the running accuracy and the height tolerance are decisive for the quality of a rolled sheet.

Cluster mills are cold rolling mills in which strips of stainless steel and non-ferrous metals are formed. To ensure that the deflection of the work roll is very low, it is supported by intermediate rolls and support axles. KRW support roller bearings are used on the support axles. Usually several support roller bearings are located next to each other on the support axle separated by support saddles.
