Most premature bearing failures can be avoided. Causes include improper mounting, mishandling, poor lubrication, entry of foreign particules/contamination and abnormal heat generation.

If all conditions are known both before and after the failure, including the application, operating conditions and the environment, then a countermeasure can be determined by studying the nature of the failure and its probable causes.

Examples of bearing damage and countermeasures are presented in the following sections.
