It is known that the presence of particles in the lubricating fluid additive or wear products, and also due to its molecular orientation of the wall near the solid support surface bearing lubrication is separation into layers of different viscosities. Laminar flow of a viscous incompressible fluid in the gap of the thrust and radial bearings considered in [1-16]. A significant drawback of the proposed methodology here is that the computational model is ignored pressure dependence of viscosity. For large values of the pressure in the lubricating layer of lubricant viscosity increases significantly, and there is a need to address the dependence of viscosity on pressure.
