This paper presents an analytical solution of velocity components of unsymmetrical oil flow and pressure distribution in radial journal bearing gap for hydrodynamic unsteady lubrication with viscoelastic oil. Numerical calculations are performed in Mathcad 11 Professional Program, with taking into account the method of finite differences. This meŹthod satisfies stability conditions of numerical solutions of partial differential equations and values of capacity forces occurring in cylindrical bearings. Exact calculations of presŹsure in journal bearing and its load capacity may be useful to prevent from premature wear tribological units of self ignition engines, especially those applied in ships.
