  • Slewing bearings - SKF

    Bearing rating life for rolling bearings. The fatigue life of an individual bearing is the number of revolutions (or the number of operating hours at a constant speed) that the bearing operates before the first sign of metal fatigue (rolling contact fatigue (RCF) or spalling) occurs on one of its rings or rolling elements.

    Abstract During the operation the slewing bearings are a subject to a large deformation. It is the cause of unequal load of the rolling elements. Deformation of the bearing can be calculated by the FE models, in which the rolling elements are replaced by the truss elements. These elements ought to have a right load–deformation characteristic.
