The methodology of calculation of hybrid (metal-polymer) sliding bearings by load capacity, durability and wear of the bushing made of reinforced polymer composites, in particular polyamide filled with glass or carbon dispersed fibers, is presented in the article. The technique of model triboexperimental studies is presented. Based on the results of these studies, the wear resistance diagrams of the investigated tribocouples of bearing materials were constructed and the characteristics of their wear resistance were determined. The specified contact and tribotechnical parameters have been calculated. Quantitative and qualitative regularities of their change from the main studied factors of influence are established: load, bushing diameter, radial clearance. Empirical relationships between maximum contact pressures and durability are determined depending on the factors specified.
