Purpose of this paper is to present the magnitude of the impact of roller bearing rings mutual slewing to the process of contact stresses in rolling elements. The roller bearing satisfies prescribed basic static load rating if it is loaded by the maximum specified load only in the radial direction according to the ISO/TS 16281. However, the real roller bearings are not loaded only in the radial direction in practice. During operation there is mutual slewing of the bearing roller rings. This leads to a change in the conditions of contact and to a change in contact stresses. Stress state will be evaluated in the most loaded element of the roller bearing. Equivalent stress will evaluated according to the theory of HMH, stresses P1 to P3 at gradual slewing of the roller bearing rings, angle ϕ from 0' to 8'. For the analysis of this problem was used the finite-element program ADINA.
