Abstract
A straight line which, when extended, passes through the origin of coordinates is obtained when the coefficient of friction for a full journal bearing operating in the thick film region is plotted against μN/P, where μ is the lubricant viscosity, N the journal speed, and P the bearing load per unit of projected area. At higher speeds, when the film temperature around the bearing is not reasonably uniform, large deviations from this line are found. An increase of friction, which qualitatively confirms the theory developed in part I of this series, is observed when the strength of the source of lubricant is increased.Keywords
