The definition of static and dynamic load capacities according ISO 76 and ISO 281 are valid for steel bearings only. Now an extension of these standards is available for hybrid bearings with ceramic rolling elements in DIN ISO 281 Supplement 5 and DIN ISO 76 Supplement 2. For the dynamic load capacity the values for fc and bm are changed, for the static load capacity the value of f0 is changed.

This option for calculation of load capacities of hybrid bearings will be available in the next version of MESYS Rolling bearing calculation.
