X-life ultra Bearings were designed for maximum demands on speed-ability and load. They are Hybrid Bearings with rings made of Cronidur 30, a high nitrogen stainless steel. Compared to the conventional rolling bearing steel 100Cr6, Cronidur 30 exhibits a substantially finer structure, thus ensuring cooler operation and higher admissible contact pressure. Tests of the material fatigue life exceeded the calculated values by such a large degree that it can be considered practically fail-safe in the field of application. Under mixed friction conditions, this steel also lasted up to 10 times longer than the standard material 100Cr6. This steel is likewise significantly superior to conventional rolling bearing steels in terms of Hertzian compression strength, corrosion resistance and hot hardness. Compared to conventional bearings,the extended service life of X-life ultra Bearings makes an enormous contribution to reducing system costs. In principle, all Spindle Bearing designs are available as X-life ultra Bearings. To take full advantage of the performance capability of X-life ultra Bearings,the structure surrounding the bearing arrangement must be designed appropriately.
