WebOct 7, 2024 · It is caused by running the bearing at load above the fatigue limit. If load acting to the bearing is higher than the fatigue strength of the material, fatigue cracks form on the bearing surface, spread towards the back layer and may result in peeling off the bearing material. Possible causes of fatigue: WebContact Fatigue. Contact fatigue is the most important failure mode for rolling element bearings. Depending on the initial causes, it can have different appearances, ranging …
