Hot summer is comming. Rock cruhser users always have the problem of bearing overheating. As rock crusher's crushing work is a revolving process driven by the electric engine, it will make the engine become overheating when the crusher revolves for too long time. This will affect working efficiency of rock crusher.
Then what to do with this problem? 1. Keep regular lubrication. 2. Don't add too much oil. Too much oil may cause bearing overheating. 3. The bearing itself may be wore down. 4. When the bearing covers too tight, it will cause large frictional force and overheating.
