• There are many reports in regard to oil film properties in the journal bearing, most of them based either upon infinitely long bearing approximation or upon infinitely short bearing approximation. Experimental results obtained by using full journal bearings with length-diameter ratio λ equal to unity did not show a good coincidence with analytical results derived by infinitely long or short bearing approximation, but they were found to agree well with exact solutions of finite bearing. Here is introduced a finite bearing approximation which depends on a simple assumption for axial pressure curve. This approximation can take less time for digital computation than the exact solution. Stationary properties of oil film bearing given by this approximation coincide well with the exact solution for a finite bearing with a wide range of λ=0〜∞.
