To test the validity of the theory, described in Part I of this investigation, calculations are performed for a cylindrical, two-axial groove journal bearing over a range of loads and speeds. The results give the temperature distribution in the lubricant film and in the bearing sleeve, the journal surface temperature, the heat balance for the bearing, the journal center eccentricity, and the film pressure profile. The calculated results are compared with experimental measurements, and although significant discrepancies are observed, the overall agreement is satisfactory, considering the usual tolerance effects and the uncertainties in defining some of the design parameters
