The staircase method is of the statistical method used in fatigue testing. Compared with the Weibull method which is usually used in bearing life tests, the staircase method can reduce testing time. In 0rder to study the possibility of application of the staircase method in bearing life tests, experiments on the 51 103 thrust ball bearings were conducted. It is confirmed that the expected values of the mean and standard deviation estimated from the results of 20 specimens based on the staircase method approach the population parameters. In this study, it is verified that the basic dynamic load rating obtained by the staircase method was similar to that obtained by the Weibull method and that obtained from calculations according to ISO 28l: 1990. Compared with the standard deviation estimated by the staircase and Weibull methods, the results obtained by boundary and arcsin methods had larger values.
