Based on dynamic theory of roller bearing, considering variable real-time contact force and rotational velocity of roller bearing, a numerical simulation model of wearing for cylindrical roller bearing was established by the method for wear numerical simulation of components, and the wear lifetime of cylindrical roller bearing was predicted. An example was adopted to verify that the result of simulation. The results show that the result of simulation is consistent with that of real wear. The numerical simulation method can be used to predict the wear lifetime of cylindrical roller bearings.
