The technical level and quality of aviation bearings have a direct impact on the performance of aeroengine,therefore, the development of highly reliable aviation bearings is particularly important for ensuring aviation equipment performance and pilot safety. This paper describes the current status of the aviation bearing technology at domestic and overseas, analyzes the technical gap between domestic and overseas from the aspects of material, design, manufacture, testing and so on. Based on the higher temperature, bigger load, faster speed, longer life and more reliability of aeroengine, the future development of the aviation industry, the research direction of aviation bearing technology which should be solved and developed are put forward, such as the application of new materials, surface treatment, structural design and simulation, intelligent manufacturing and testing, experimental technology and evaluation, and smart bearing technology.
