Vibrating screen bearing failure

The correct use and careful maintenance can prevent the bearing from heating and burning to improve the design and processing quality of the vibration exciter. The vibration exciter is the power source of the vibrating screen and is subjected to strong vibration and shock. Practical experience shows that the main bearing damages are as follows
