| Description |
Investigation showed that the turbine front bearing has failed by true brinelling followed by severe spalling on the inner raceway. The most probable reason for such failure appears to be excessive load on the balls arising from the misalignment of the bearing. The cause for the misalignment is uncertain and needs to be determined to prevent recurrence of similar failure. The microstructure and hardness of outer/inner ring and the balls were found to be in the normal range of high carbon bearing steel. There were no damages in the turbine rear bearing.
