In this paper a theoretical and experimental work for design of plain journal bearing able to work up to severe conditions is reported. The mathematical model and the numerical methods on which a purposely developed computer program is based are firstly described. The program is aimed to the evaluation of the behaviour of hydrodynamic plain journal bearings under heavy static loads, considering the elastic deformation of the bearing members, geometrical errors such as the axis misalignŹment and thermal effects. The experimental apparatus designed and set up for testing plain bearings in several working conditions, by varying speed, load and oil supply up to extremely critical situations, is then briefly described. Theoretical and experimental results obtained at different load, speed and oil flow rate conditions are finally compared showing a good agreement.
