The purpose of this study is to make clear the distribution of oil film pressure due to the squeeze film effect in comparison with one due to the wedge film effect. In the experiment, by making use of strain gauges, we measure at first the pressure distribution of oil film in a journal bearing when the journal rotates at a constant angular velocity under constant load. Next, we investigate the relation between the motion of the journal center and the distribution of oil film pressure which is caused by the whirling motion of the journal. In the analysis, we get the solution of oil film pressure for an infinitely long bearing under the boundary condition which is clarified experimentally. Based on this solution we analyse the variation in the pressure of oil film caused by small circular motion of journal center. The analytical results are found in good agreement with the experimental ones.
