WebJan 19, 2016 · True Brinelling – points to a bearing load that exceeded the elastic limit of the bearing material. False Brinelling – takes the form of a depression around the race … False brinelling is a bearing damage caused by fretting, with or without corrosion, that causes imprints that look similar to brinelling, but are caused by a different mechanism. False brinelling may occur in bearings which act under small oscillations or vibrations. The basic cause of false brinelling is that the design … See more In normal operation, a rolling-element bearing has the rollers and races separated by a thin layer of lubricant such as grease or oil. Although these lubricants normally appear liquid (not solid), under high pressure they … See more False brinelling was first mentioned by Almen in 1937. Almen found that wheel bearings were damaged before they were used by customers. Furthermore, he found that the bearings … See more The simulation of false brinelling is possible with the help of the finite element method. For the simulation, the relative displacements (slip) between rolling element and … See more • Emerson Bearing picture of false Brinelling • Precision Spindle explanation of false Brinelling • MRO Today on rotating spares • US Motors service bulletin case study, explanation, and pictures (PDF) See more
