Bearings that are not operating properly usually exhibit identifiable symptoms. Here will be presented some useful hints so that it can perhaps be prevented from happening again.
The listed causes are the most common for the symptoms, see section Typical symptoms indicating impending bearing failure.
Practical solutions are presented wherever possible. Depending on the degree of bearing damage, many misleading symptoms may be present.
In most cases these symptoms are the result of secondary damage. To effectively troubleshoot bearing problems, it is necessary to analyse the symptoms according to those first observed in the applications.
Additional solutions appear in the section Bearing failures and their causes.
