Why a bearing failed can be identified many times by tell tale wear patterns on the bearing components.
Reliability can be improved if corrective actions can be implemented from the findings of bearing analysis. To see what kind of analysis L&S Electric provides, please read this PDF of a sample Bearing Analysis Report.
Motor’s sent in for repair which you want bearing analyzed:
Should your company send a motor into the shop which had failed prematurely or has a history of reliability issues please tag it to have bearings analyzed. Bearings then are saved for analysis and orientation marked during disassembly.
Bearings are analyzed before repairs are completed so corrective actions identified during bearing analysis can be implemented during the repair process to return to you a more reliable motor.
Or,
Bearing being sent in for Analysis:
Should you company have a bearing on-site for any application which fails prematurely or has a history of reliability issues save that bearing for analysis. Do not clean off any of lubricant and place in a plastic zip bag. Mark orientation, which side was facing out, on the bearing raceway. Provide your contact information if additional data on the identification of the unit and application is needed during the analysis.
