1. Lubricants or grease varieties are not selected;
2. Lack of lubrication (oil level is too low, oil or grease leakage through the seal);
3. Bearing clearance is too small (with the selection is not appropriate);
4. Bearing mixed with sand or carbon particles and other impurities, played the role of abrasive;
5. Bearing mixed with water, acid or paint and other dirt, play a corrosive effect;
6. The bearing is flattened by the seat hole (seat hole roundness is not good, or seat hole distortion is not straight);
7. Bearing the bottom of the horn uneven (resulting in deformation of the seat hole or even the bearing block cracks);
8. There are debris in the bearing seat (residual chips, dust, etc.);
9. Seal eccentric (touch adjacent parts and friction);
10. Bearings subject to additional load (axial bearing by the tight, or an axis with two fixed-end bearings);
11. The bearing is too loose to fit with the shaft (the diameter of the shaft is too small or the adapter sleeve is not tightened);
12. Bearing clearance is too small, too tight when rotating (tight set too tight set too);
13. Bearing noise (roller end or ball skid caused);
14. The thermal elongation of the shaft is too large (the bearing is subjected to static and indeterminate axial load);
15. The shoulder is too large (hit the bearing seal and friction)
16. Block hole too big to the shoulder (the bearing of the seals hit the distortion)
17. Labyrinth seal gap is too small (with the shaft friction)
18. Tightening of the washers of the lock washer (contact bearing and friction)
19. Sling the location of the oil ring inappropriate (hit the flange cover and friction)
20. Steel ball or roller on the pressure pit (installed with a hammer knocking bearing caused)
21. Bearing noise (with external vibration source interference)
22. Bearings change color and deformation (using the gun to remove the bearings caused by heating)
23. The shaft is too thick to make the actual fit too tight (causing the bearing temperature is too high or noise)
24. Block hole diameter is too small (resulting in bearing temperature is too high)
25. Bearing hole diameter is too large, the actual cooperation is too loose (bearing temperature is too high - outer ring slip)
26. Bearing hole becomes larger (non-ferrous metal bearing hole is stretched, or due to thermal expansion and larger)
27. Bearing noise (bearing a fretting wear)
