On regular maintenance of the equipment, operation of FAG bearings and bearing of the perimeter when replacement parts are removed when a check is made, you need to determine whether the FAG bearing parts in sequence can be used again and record usage better than bad. Careful investigations and records were also broken down bearing and appearance. In order to identify and investigate remaining amount of lubricant, after sampling, to properly clean the bearings.
　　Secondly check the FAG bearing Raceway surface, rolling surface and surface condition and cage wear, no damage and abnormalities in particular to observe the running track of the Raceway surface. Judgment bearing will use again, to bearing damage level of machine performance, importance, condition, inspection cycles later to decide.
　　Check the results, if when FAG bearing is damaged and the anomalies are found, follow the phenomenon identified cause of bearing damage, to formulate policy responses. Also, check the results, if there is several defect, bearings, can no longer be used, and new bearing needs to be replaced.
　　A. cage wearing serious or rivets loose badly.
　　B. rolling body Raceway surface, rust and bruises.
　　C. scroll, scroll bars, a significant indentation and trace on the body.
　　D. diameter of the inner ring, or creep on the outer ring outside diameter.
　　E. overheating color ill.
　　F. grease seal of FAG bearings seals and shields to serious damage.
　　G. inner and outer rings, rolling elements, cages any one there are cracks and debris.
　　H. inner and outer rings, rolling elements in which any split.
　　I. Raceway surface, rib, rolling card significantly hurt.
