The paper presents a method for forming exact self-similar solution of the problem of calculating the compliant hydrodynamic journal bearing of finite length, running on layered lubricant in the axial lubrication. On the basis of the equations of motion of a viscous incompressible fluid, continuity equation and Lame equations for the case of a "thin layer" found the velocity and pressure, analytical expressions for the components of the supporting forces, the forces of friction and resistance forces axial movement of the lubricant. The analytical expressions for the value of the lubricant in the axial direction. The estimation of the parameters characterizing the ratio of the viscous layer adapted profile and the deformation of the elastic layer on the basic performance of the bearing. Established the most rational of the bearing capacity, the force of friction and lubricant consumption values ​​of these parameters.

Keywords: radial bearing, load bearing capacity, stratified flow
