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.

Keywords: Adapted profile, stratified flow, load-bearing capacity, the friction force, the Couette flow
