The axial load of aero-engine angular contact ball bearing is an important parameter during the engine design. Therefore, it is very important to specify the value and direction of actual axial load for the safety and reliability of the bearing. To obtain an indirect measurement method for axial load of angular contact ball bearing, the key influence parameters analysis based on similarity principle and dimensional analysis which can be operated easily for real-time monitoring is presented in this paper. This method can obtain each component of axial load, which is helpful for the analysis and adjustment of axial load. The measurement results are compared with those of load cell measurement in bed tests. It was found that the results obtained by these two methods are in good agreement, and the relative difference is within the acceptable range. The indirect measurement method can be applied in engineering.
