Typical symptoms indicating impending bearing failure
Below is a list of the seven most common symptoms produced by bearings that are not operating properly. The list in section Symptoms and typical conditions provides a summary that identifies 51 typical conditions for the symptoms.
Seven sections, one for each listed symptom, give information about probable "Reason for condition" and offer "Practical solution".
How to use the troubleshooting chartsAs an example, A in the column "Symptoms" in section Symptoms and typical conditions represents a bearing that is overheating. By scanning the list at least 29 possible conditions will be found indicating an overheated bearing.
Either go directly to the section Overheated bearing, or first note a few probable conditions from the list and the corresponding "Solution Code." (More than one condition may be found that applies to the application.) Then turn to the section Overheated bearing. Use the solution code(s) to determine the probable cause of the overheated bearing.
|C||Replacements are too frequent|
|E||Unsatisfactory equipment performance|
|F||Bearing is loose on the shaft|
|G||Shaft is difficult to turn|
