Without disassembly inspection, can identify or predict the operation of the bearing has no fault, to improve the productivity and economic is very important.

The main identification is as follows:

1) to identify by sound

Through the voice recognition, the need for a wealth of experience. Must be fully trained to be able to recognize the sound of the bearing and non bearing sound. To this end, because as far as possible by professional people to work on it The sound of the bearing can be clearly heard on the outer shell with the listening stick.

2) by working temperature identification

The method belongs to the comparison method, which is limited to the situation where the running state is not changed. Therefore, temperature must be recorded continuously. When a fault occurs, the temperature will not only rise, but also irregular changes. The method is suitable for the method of sound identification.

3) through the identification of lubricants

The lubricant sampling and analysis, through the degree of pollution, whether mixed with foreign bodies or metal powder, etc.. The method can not be close to the observation of the bearings or large bearings are particularly effective.

The bearing can not be directly observed in operation, but through the noise, vibration, temperature and lubricant condition check bearing abnormal.
