1. Bearing bending

Solution: Improper axle shoulder may cause bearing bending. It is necessary to reprocess the shaft chamfering or add shoulder clasp to eliminate stress.

2. Insufficient bearing support leads to distortion of the outer ring

Solution: Rework the chamfering of the bearing box or add shoulder clasp to eliminate stress.

3. Friction occurs between the shaft shoulder and the bearing

Solution: Rework the shoulder to eliminate friction

4. Bearing seals are deformed

Solution: Reprocess the empty shoulder of the bearing box.

5. Deformation of shaft and inner ring

Solution: Reprocess the shaft chamfering to obtain proper support.

6, bearing box and outer ring deformation, bearing extrusion

Solution: Reprocess the chamfering of the bearing box to obtain proper support.

7, rotating oil seal or dust ring friction static parts

Solution: The operating clearance of rotary oil seal and dust ring should not be too small to avoid friction and borrowing.

8, the oil level is not correct, there is no lubricant in the bearing

Solution: Clean up the blockage in the oil level table to make the oil level correct.
