Inadequate maintenance practices associated with misalignment and shaft tilting influence contamination related failures, due to large shaft orbits that develop.
Using Vibration Analysis To Detect Early Failure Of Bearings - …
Bearing engineers generally use fatigue as the normal failure mode, on the assumption that the bearings are properly installed, operated and maintained. Today, because of improvements in manufacturing technology and materials, bearing fatigue life, which is related to sub-surface stresses, is not the limiting factor and accounts for less than 3% of failures in service.
