As the center of bearing supply, the conveyor bearings suppliers know well about bearings. How to judge the operation of bearings can be preliminarily understood by the following three methods.

First of all, it can be judged by the sound of bearings. According to the experience of the conveyor bearings suppliers, bearings will have rolling sound in use. The size and sound quality of the rolling sound of bearings in operation are checked by a microphone. Even if the bearings have slight peeling damage, abnormal and irregular sounds will be emitted, which can be distinguished by a microphone.

The second is the vibration of the bearing. Bearing vibration is very sensitive to bearing damage, such as spalling, indentation, rust, cracks, wear and tear, etc. It can be reflected in bearing vibration measurement. Therefore, the vibration can be measured by using a special bearing vibration measuring device (frequency analyzer, etc.), and the abnormal situation can not be inferred by frequency. The measured values vary with the use conditions of bearings or the installation position of sensors, so it is necessary to analyze and compare the measured values of each machine before determining the judgment criteria.

Finally, the temperature of the bearing. Generally, the temperature outside the bearing chamber can be inferred by the conveyor bearings suppliers. If the oil hole is used, the temperature of the bearing outer ring can be measured directly.
