Bearings are important accessories on stone crushers, and their performance directly affects the normal operation and production efficiency of stone crushers. During the operation of stone crushers, special attention should be paid to the temperature rise of bearings and the noise of bearing parts. If there are any abnormalities, they should be handled as soon as possible. So what are the causes and solutions for heating of stone crusher bearings?

1. The two bearing seats are uneven, or the motor rotor and the crusher rotor are not concentric, which will cause the bearings to be impacted by additional loads, thereby causing bearing overheating. If this happens, the machine should be stopped immediately to eliminate the fault to avoid premature damage to the bearings.

2. Too much, too little or aging of lubricating oil in the bearings are also the main causes of bearing overheating and damage. Therefore, lubricating oil should be added on time and quantitatively according to the requirements of the instruction manual. Generally, lubrication accounts for 70%-80% of the bearing space. Too much or too little is not conducive to bearing lubrication and heat transfer.

3. The bearing cover and bearing are too tight, and the bearing and shaft are too tight or too loose, which will cause bearing overheating. Once this problem occurs, this problem will cause friction noise and obvious swing during the operation of the equipment. Stop the machine, remove the bearing, repair the friction parts, and then reassemble as required.
