Generally speaking, we should pay attention to the following points from the point of view of use:

1.Bearing clearance should be appropriate, too large impact, too small lubrication is bad, may burn tile;

2.The surface quality and geometric shape of bearings and journals should be strictly guaranteed.

3.Improve lubrication quality, control oil pressure, temperature and flow rate, and strengthen oil filtration;

4. Use fuel oil and lubricants that meet the requirements.
