introduction：INABearing working hours，Rolling element and inner ring（Or ring）The load is not constant，It changes over and over again with the running of the bearing。This load is an alternating load；Also due to the rolling element and inner ring（Or ring）The contact area is very small，Makes the contact stress very high，At higher RPM，Under the repeated action of huge alternating contact stress，The metal will fatigue。initiate，Small cracks can be seen where the stress is concentrated，Due to the role of lubricating oil and metal corrosion，Cause the crack to expand gradually，When expanded to a certain extent，The surface metal will peel off，Form small pits，Similar pitting，When we were disassembling the bearings，Pitting and peeling pieces of metal will often be found on the inner or outer ring and the surface of the rolling body，This is the phenomenon of metal fatigue peeling。 INAThe fatigue spalling of the bearing occurs if the bearing runs for a long time，Should be considered natural damage，If it occurs in the middle or early s
