The most glaring problems in reality in the field of finite element analysis of tapered roller bearings are long calculation time and great error due to neglect of axial force. The static condensation method and solving technique are introduced in this paper to reduce the calculation time and raise the calculation precision. Due to the effects of axial force, the contact boundary becomes more complicated. Up to now, the paper dealing with axial force is rarely seen. This paper mainly studies four-row tapered steel mill bearing under reality loaded condition with finite element analysis and computation method. The contact load-distribution given by finite element calculation is in agreement with photo-elastic experiment. This paper also supplies a fast and effective numerical method for finite element analysis of many other types of bearings.
