As one of the causes of damage of rolling bearing used under small load, the poor lubrication between rollers and cage has been pointed out. When this poor lubrication occurs, abnormal abrasion of cage occurs, which may result in seizure of bearing eventually. In order to prevent the seizure of bearing, it is important to understand the mechanism of damage of rollers and cage. However, the behavior of bearing in the poor lubrication has not been made fully clear. Therefore, in this research, behavior of bearing when the poor lubrication between rollers and cage occurs has been investigated by a rotation test of cylindrical roller bearing. As a result, it has been clarified that vibration acceleration and temperature of the bearing increase quickly by the breakage of the oil film just before seizure of bearing, and abrasion of cage proceeds after increase in vibration acceleration has occurred.
