The general trend towards plant with higher productivity is also apparent in larger production systems. As a result, there is increasing demand for correspondingly high performance components and sub-assemblies of larger dimensions.

The challenges here are not only technical but also commercial in nature and may vary widely. Components for bearing arrangements are among the machine that make a decisive contribution to the overall performance of a system. For bearings in machine tools, the important parameters are not only the load carrying capacity but also the accuracy, rigidity and speed capacity. On the part of machine manufacturers, this is expanded by the use of complete machining and also process integration.
