During the use of the vibrating screen bearing, the temperature rise is too large and the bearing is easily damaged. Cause Analysis:
it is full range of valve seat for the following type :

1: If it is a new sieve, it must be a process problem, if it is old sieve, stiffness, foundation, etc.
2: The lubrication system is a problem
3: The bearing clearance should be properly selected
4: Is the bearing manufacturer qualified?
5: Processing accuracy. Due to the lack of precision in domestic processing, three sets of large clearance bearings are used. The use of such bearings is at the expense of increased noise.
6: Bearing cooperation, reasonable selection of bearing fit, affect bearing heat and life.
7: The structural design is unreasonable.
8: The center of gravity of the sieve is too large
9: Unreasonable lubrication, or too much or too little oil
10: Whether the bearing is installed correctly or not, the tolerance is reasonable or not, it is the key to heat generation.
