Pressure distribution has been measured and analyzed to clarify the fundamental characteristics of ""continuous oil-film"" formed in transparent journal bearings, into which oil in general use is supplied. The results are as follows : (1) Sommerfeld's distribution for perfect oil-film is approximately observed only under limited conditions : low eccentricity and low speed. Measured pressure mostly shows quasi-Sommerfeld's distribution, which is characterized by downstream shift of pressure profile and underdevelopment of pressure trough compared with Sommerfeld's distribution. (2) Calculated pressure, taking account of compression and expansion of fine bubbles in a lubricant, shows qualitative agreement with experimental data. This would suggest that the behavior of bubbles constitutes the characteristics of continuous oil-film and remain to be further studied.
