Abstract In order to improve the service life and reliability of aerospace bearings，the high cycle rotating bending fatigue properties and failure modes of high cobalt molybdenum stainless bearing steel at different temperatures were studied. With the increase of temperature，the fatigue limit strength of steel decreased gradually. The fatigue limit strength of the steel was 927，840 and 667 MPa respectively under the condition of 25，300 and 500 ℃. The fatigue limit strength of the steel was reduced by 9.4% and 28.0% respectively at 300 and 500 ℃. At 25 ℃，the crack initiation was caused by surface ravine resulting in stress concentration. When the temperature rised to 300 ℃，the hardness of the fatigue specimen decreased and the persistent slip bands appeared under the action of long time alternating stress. At 300 ℃，carbides precipitate and growth accelerated crack initiation. At 500 ℃，the hardness of the matrix continued to decline，so that the persistent slip bands were more likely to occur. Under the action of thermomechanical coupling，the carbides on the edge of the fatigue specimen precipitated，and the carbides growed when heated for a long time. The carbides interacted with the dislocation and produced tiny cracks on the edge of the carbides in the persistent slip bands. The precipitation and growth of carbides accelerated the propagation of fatigue cracks.
