It needs to withstand high temperature, high pressure and severe vibration. Therefore, the slewing bearing in the aircraft engine needs to undergo high-temperature resistance testing during processing. In the high-temperature resistance test of the slewing bearing in the aircraft engine, in order to simulate its actual operating conditions during engine operation, the inner ring needs to be rotated. When the aircraft engine is running, the inner ring of the slewing bearing needs to rotate at high speed with the components. Only by simulating this state in the test can its performance under high temperature be accurately tested. However, due to the large differences in specifications and sizes of various models of slewing bearings, the number, position and aperture of the fixing holes are all different.
