Lubricant Failure = Bearing Failure | Machinery Lubrication

Lubricant-related failures can be avoided by selecting a grease or oil that generates a sufficient film to keep bearing elements separated. A good lubricant also provides good boundary lubrication. Lubricant failures can be detected by the presence of discolored (blue/brown) raceways and rolling elements.
