Hi James. Thank you for your question!

　　Possible causes of failure

　　1. It indicates that the bearing is short of oil and needs to be refueled in time. Of course, too much refueling will make the bearing hot. We must check the oil level when refueling.

　　2. Bearings at both ends of the main shaft of jaw crusher are usually lubricated with lithium-based grease. Dirty grease will also cause bearing heating.

　　3. The bearing is damaged.

　　4. Cover tightly.

　　The relative solution is:

　　1. Check whether the oil is appropriate, increase or decrease according to the situation.

　　2. After cleaning the bearing, replace the grease.

　　3. Replace the bearing.

　　4. Adjust the bolts properly.
