Summarize for you 30 bearing ring causes
- Aug 01, 2016 -

Harbin bearing little numbered summary 30 bearing ring causes:

1. bearings in mixed with water, acid or paint, dirt, corrosion;

2. the bearing hole clip flat (bore roundness is poor, or bore distortion of straight);

3. the Horn of the underside of the housing injustice (lead to deformation or cracks on housings);

4. debris in the bore of the bearing (residual chips, dust, etc);

5. oil impurities;

6. lack of lubrication (oil level is too low, save the improper oil or grease leakage by sealing);

7. bearing internal clearance is too small or too large (factory);

8. mixed with sand or carbon particles and other impurities in the bearings, an abrasive role;

9. seal eccentricity (run into adjacent parts and friction);

10. additional bearing loads (axial of the bearing stand tight, or two locating bearing on the shaft);

11. the bearing and shaft fit too loose (the smaller diameter of the shaft or sleeves are not tight);

12. bearing internal clearance is too small, rotating too tight (adapter sleeve tighten too far);

13. the bearings have noise (caused by skidding of the end roller or ball);

14. the thermal elongation of the shaft is too large (indeterminate axial bearing load);

15. the shoulder is too large (encounter seals bearings and friction);

16. seat the abutment is too big of a hole (touch distort bearing seals);

17. the labyrinth sealing ring gap is too small (with the shaft friction);

18. bend tooth lock washers (met bearings and friction);

19. oil ring location is inappropriate (encounter friction cover and flange);

20. the pit on the ball or roller (installed with a hammer when the bearing caused by);

21. the bearings have noise (external vibration interference);

22. heat discoloration and deformation of the bearing (use gun to heat caused by disassembling bearing);

23. the shaft too large so that the actual suit too tight (bearing temperature or noise);

24. small hole diameter (bearing temperature is too high);

25. the bearing bore diameter is too large, practical cooperation is too loose (temperature is too high-the outer ring of bearings slipping);

26. the bearing bore larger (non-ferrous metal bearing block hole is stretched, or larger due to thermal expansion);

27. the cage fracture.

28. bearing Raceway rust.

29. the steel ball, roller wear (grinding of sub-standard products have hurt).

30. the unqualified Raceway (production plant).
