the wearing of the rolling bearing is actually associated with both randomness and fuzziness. In this paper, we analyze the fuzziness of the experimental data of the wearing life of the rolling bearing and discuss its fuzzy subsets, membership function and fuzzy identification. We take the wearing life of the 102 rolling bearing for example, study the normal fuzzy set and three-parameter Weibull fuzzy set and conduct the identification for the probability distribution. In particular, we also develop an innovative method to identify the experimental data of the wearing life of the rolling bearing.
