Q: Why does the roller bearing overheat
A: Overheating of cylindrical roller bearings usually indicates that the cylindrical roller bearing is already in an abnormal condition. High temperatures are also harmful to bearing lubricants. Sometimes bearing overheating can be attributed to bearing lubricants. Long-term continuous rotation of the bearing at a temperature exceeding 125 ° C will reduce the bearing life. Causes of high-temperature bearings include insufficient lubrication or excessive lubrication, impurities in the bearing raceways, excessive limit speeds, and long-term overload operation of the bearings.
