Popis:	The paper presents a modeling of angular bearing in the context of motion resistance. It was assumed that the motion resistance depends on the contact forces. For that reason, the main goal of modeling was an estimation of the forces and determination of the influence of such parameters, like rotational speed of the bearing ring, pre-displacement of the bearing and fit of the shaft and the inner ring, exerted on those forces. In the literature, when estimating the contact forces, such parameters are taken into account very rarely. The modelling was performed by means of a numerical method, viz. FEM. The modeling results show that the omission of such parameters will lead to big errors in estimation of contact forces, and those errors may be as high as 100%, or even higher. The real motion resistance will be bigger than calculated.
