In this paper, based on the Navier-Stokes equations in the case of a "thin layer" is a method of forming an exact self-similar solution of the problem of calculating the hydrodynamic thrust bearing with the adapted profile of the supporting surface, running on a two-layer lubrication, c considering the viscosity of lubricating fluid temperature. Found the velocity and pressure in the lubricating layers and using the expression for the rate of energy dissipation analytical expressions for the viscosity of the lubricating layer. The estimation of the influence of parameters characterizing the adapted profile of the bearing surface of the bearing, and temperature parameters, viscous layers of relationships and their length on the basic performance of bearings operating on stratified lubricants. The optimal values for these parameters to ensure the rational, for bearing capacity and strength of friction operation under consideration thrust bearing.

In this paper, taking into account the interactions of the layered conductive lubricant with a solid support surface is given by the method of calculation of the radial sliding bearing with the increased bearing capacity. Here, based on the Navier-Stokes equations, the equation of continuity and the Lame equation for the case of a "thin layer" provides a method of generating an exact self-similar solution to the problem. The problem solution is resulted in identifying the velocity and pressure field in the lubricating layer and subsequently found analytical expressions for the basic performance of the bearing. The estimation of the complex parameters that characterize different aspects of tribosystem, such as the parameter characterizing the layered nature of the lubricant; the supporting surface adapted profile; conductive properties of the lubricant; the electric field and the magnetic induction on the basic performance characteristics of the radial bearing.
