In order to carry out basic research on the life of aviation bearings, aeroengine bearing tester has been developed. The tester has the temperature, speed, load and other parameters of the automatic control of spectral lines run and test the characteristics and functions of automatic alarm. The structure and performance of the tester are introduced and its high-speed test performance is verified. The results show that the tester meets the test requirements under harsh working conditions of the aviation intermediate bearing, realizes the automatic control of the test run, real-time monitoring and storage of process parameters, Can be used as the basis of aviation intermediary bearing experimental research platform.
