During opreation, the temperature of the Jaw Crusher's bearings can be really high, somewhat 100 centi-degree or even higher. The reasons to cause such a problem are as the following:
1. The bearing is lack of lubricant oil
Solution: Add more lubricant oil into the bearing cover.
2. There are inpurities in the lurican oil in the bearing cover
Solution: Replace the oil with new clean luricant oil.
3. The bearing is broken.
Solution: replace the bearing.
