Bearing Failure Analysis
As a result, internal components such as the raceway and ball bearings experience wear. The service life of the lubricant should be matched to the service life of the bearing. For example, if a bearing has an expected life of 2,000 hours using standard grease, you can extend the life of the bearing by 10% to 20% if you use a higher-grade ...
