In the use process because of their quality and external conditions, the bearing capacity, the rotating precision and antifriction properties will change, when the performance of bearing below using the request fails to work properly, it is called bearing damage or failure, bearing upon the occurrence of damage and other accidents occur, there will be the machines, equipment shutdown, function is abnormal damage etc..
Therefore need the investigation took place in the short term, and take corresponding measures, of course, the rolling bearing damage mechanical parts than the average damage is much more complex, bearing damage is characterized by manifestation, the reasons are complicated, bearing damage in addition to internal factors bearing design and manufacturing, mostly due to the use of improper selection, such as: cloth for (see customer notice), supporting the unreasonable design, improper installation, poor lubrication caused by external factors, such as the seal is not good.
It is very important to study the formation and reasons of rolling bearing damage, on the one hand can be improved by using the method, the proper use of bearings, gives full play to the efficacy of bearing, new products contribute to the development of better performance, on the other hand. In addition to the rolling bearing the points for attention in use, installation, operation and supervision etc, also introduces the form and cause of bearing damage and countermeasures that should be adopted.
