Abstract: In this paper, the theoretical calculating method of high-reliability life of rolling bearings is derived, assuming that the fatigue life of bearing steel follows the three-parameter Weibull distribution. A comparison between experimental and calculated life of three kinds of tapered roller bearings shows that the experimental life agrees better with the life calculated by the new method.
