Analysis of the Damage Causes of High Speed Bearing Failure

Abstract:

High speed bearings are specified with mechanical properties, technological parameters and defined microstructure too. When these qualities are not respected in the manufacture, arise significant damage and consequently their not running ability. Cause of damage can also be bad operating conditions during its operation running. In this work microstructure characteristics are evaluated due to significant damage of the high speed bearings and thus its rejection of traffic. After microstructure investigation was not changed this microstructure but in some places micro hardness value was below the limit value, which is given by the producer and it was a consequence of bearing damage.
