Due to action of an external radial load on the bearing assembly, the load is
transferred through the rolling elements from one bearing ring to another. However, not all rolling
elements are equally involved in the load transfer from the shaft to the housing. This directly
reflects on the non-uniformly load distribution on the rolling elements, which depends on the
internal geometry of the bearing and the intensity of the external load. The main character of load
distribution on the rolling elements of a single-row rolling bearing with radial contact with and
without damage on the rolling race was analyzed in this paper. The Finite Element Analysis for a
particular ball bearing type is developed for these purposes. The influence of damage dimensions
variation, as well as external load intensity on the load distribution within the bearing is
considered. The obtained results show that when damage dimensions increase, the load
transmitted by rolling elements located just below central plane increases, while the loading on the
rolling elements whose center is in the direction of external load decreases. However, with the
increasing of the external load, and in the case of damage appearance on the rolling race, load
distribution between rolling elements become very similar to the load distribution for the case of
the bearing without damage.
