The running surface is peeled off. After peeling, it is obviously concave and convex.
Reason: The bearing rolling elements and the inner and outer ring raceways are subjected to periodic pulsating loads, resulting in cyclically varying contact stresses. When the number of stress cycles reaches a certain value, fatigue peeling occurs on the rolling element or the inner and outer ring race surfaces. If the bearing load is too large, this fatigue will be exacerbated. In addition, the bearing is not properly installed, and the shaft is bent to cause a raceway peeling phenomenon.
Solution: Re-examine the conditions of use and select the bearing and clearance, and check the machining accuracy, installation method, lubricant and lubrication method of the shaft and bearing housing.
