“Adequate lubrication SKF combined bearing is crucial for the optimal performance and longevity, which are mechanical components that integrate multiple rolling elements and usually require specialized lubrication to operate efficiently in a range of demanding applications.”However, grease lubrication has the advantage of simplifying the structure around the bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication. There are generally two kinds of fault phenomena of rolling bearing: one is that the temperature of the bearing installation part is too high, and the other is that there is noise in the bearing operation.
The rolling bearing is allowed to make slight running noise during operation. If the noise is too loud or there is abnormal noise or impact sound, it indicates that the bearing is faulty.The causes of rolling bearing noise are complex. One is the wear of the mating surfaces of the inner and outer rings of the bearing. Due to this wear, the matching relationship between the bearing and the shell and between the bearing and the shaft is damaged, resulting in the axis deviation from the correct position and abnormal noise when the shaft moves at high speed.
