In the paper selected problems of the effects of mechanical properties and shape of dry bearing sliding layer on real sliding distance of contacting surfaces have been presented. Previously described experimental results and computer simulation results presented in that paper confirmed and explained whv real sliding distance is significanlly smaller than nominal one - assumed as sum of amplitudes of oscillations measured for elements of bearing unit. Niunerical similation results are allowing to determine geometrical recommendation for sliding surface geometry of bearing material ensuring the biggest possible reduction in real sliding distance. Elastic deformation of bearing elements, having different geometry, were analysed with the application of MES. Coulomb friction law was applied to perform calculations. ANSYS programme was used for solving the problem.
