FAG bearings demonstrate advanced features a serious failure (usually miniature bearings damaged axle, Burns, Sha spallation, Raceway, wear beads and other) most of the time not more than a week, larger capacity, faster speed, shorter intervals. So, in a real FAG bearings fault diagnosis once advanced features, should be decisive judgment bearing faulty, arranged as soon as possible repair.
　　After exercise for a period of time, to maintain a certain level of vibration and noise, spectrum is single, only Yi、erbei. Little more than three times the frequency spectrum, bearing condition is very stable, enter a period of stability. Continue to run into use late, vibration and noise of rolling bearing starts to build, in some cases, abnormal noise, vibration increases more slowly, in which case the kurtosis value of rolling bearings started suddenly reaches a certain value. We believe that that performance for the early failure of rolling bearings.
　　Bearing vibration damage to the sensitive, such as spalling, indentation, rust, cracks, wear and so reflected in the FAG bearing vibration measurement, therefore, through a special miniature bearing vibration measuring instrument using (frequency analyzers) measure the size of vibration, frequency cannot be inferred by unusual circumstances. Measured value due to sensor of bearing condition of use or installation location is different, therefore requires prior analysis of each machine and compared to the standard measurement to determine.
　　Typically, FAG bearings's temperature began rising slowly running 1-2 hours in order to reach a steady state. Heat capacity at room temperature bearings for machines, cooling capacity, speed and load changes. If lubricated, install the appropriate Department, micro-bearings are a sudden temperature rise, there will be an unusually high temperature, when you stop the run, take the necessary preventive measures.
　　Temperature sensors can be monitored at any time using the bearing operating temperature and temperature exceeds the specified value, to prevent automatic alarm or stop burning shaft accident.
　　Therefore, continuous temperature monitoring is necessary, whether measured or other important parts of the bearing itself. If you are running under the same conditions, any temperature changes, can be said to be failed.
