BEARING FAILURE CAUSES AND CURES

BEARINGS Identitging and correcting causes of bearing faihue Precision ball bearings are designed to have a long and useful Iie Assuming the application is correct to begin with maximizing longevity means bearings must be properly installed lubricated and maintained Poor operating environments oarticularlv moist or contaminated areas

Rolling bearings are machine elements found in a wide field of applications They are reliable even under the toughest conditions and premature failure is very rare The first sign of rolling bearing damage is primarily unusual operating behaviour of the bearings The examination of damaged bearings reveals a wide and varied range of phenomena
