This paper describes a study on the quantitative measurement of oil film thickness in the oil impregnated sintered porous bearing by the ultrasonic method. Where, the ultrasonic method means to detect the reflected ultrasonic wave amplitude for the oil film thickness measurement. At previous studies, it was shown that the quantitative measurement of oil film thickness in the oil impregnated sintered porous bearing with inner diameter 10mm and 3mm is possible. In this study, we made it possible to measure the distribution of the oil film thickness in the oil impregnated sintered porous bearing by measuring the oil film thickness in the two orthogonal axis.
