Precautions for vibration of cylindrical roller bearings

In ordinary use, vibration is quite sensitive to bearing damage, and peeling, indentation, rust, cracks, wear, etc. will be reflected in the bearing vibration measurement. Therefore, the magnitude of the vibration can be measured by using a special bearing vibration measuring device (frequency analyzer, etc.), and the specific situation of the abnormality can be inferred from the frequency distribution. The measured values vary depending on the conditions under which the bearings are used or the sensor mounting position, so it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment criteria.
