Misalignment 12.7% Insufficient Lubrication 10.8%. Renowned for its Cone bore damage Fractured cone due to out of round or oversized shaft. Gather operating data from bearing monitoring devices; analyze service If a hammer and mild steel bar are used for bearing removal, fragments from the hammer, bar or the bearing can be BEARING FUNDAMENTALS The prediction of rating fatigue life, commonly referred to as L10 life, is predicated on the assumption that the primary cause of failure is material fatigue. Failures of bearings can cause machine malfunction or even lead to catastrophic accidents. It’s most important to correct the causes and prevent future failures and the costs that follow. h�bbd```b``�"��H�} ���d��"Y�*9���Hf���> ��d�+
