This paper describes a theory for the approximated analytical determination of pressure distribution in the gap of a generic finite length journal bearing in isothermal laminar lubrication conditions as the position assumed by the journal axis varies in a reference frame fixed in the bearing. The same theory is used to set up lubricated finite length journal bearing models in order to obtain an analytical description of the fluid film force, which is characterized by considerable prediction accuracy in the whole field defining the length-diameter ratio. In order to assess the model’s prediction accuracy, the static characteristics of the journal bearing are analytically determined. The theoretical results, presented in the form of diagrams, are compared with the corresponding results obtained numerically.
