The main identification method is as follows:

 1) identified by voice

To identify needs through sound experience.  Be adequately trained to be able to identify bearing and non bearing noise sound. Therefore, we should try to carry out this work by hand. With listening, or listening on a stick attached to the shell can clearly hear the voice of the bearing.

2) Identified by the working temperature

this method is recognition method, only with less change in the operating state of the occasion. To this end, the temperature must be continuously recorded. Failure is not only temperature, but also irregular changes.

 3)  Identify the state of the lubricant

Sampling and analysis of lubricants, through its pollution level is mixed with metal powder or other foreign matter to judge. The method can not be observed near the large bearing or bearings are particularly effective.
