1. Wheel Bearings

2. Bearing uses n Pivots n Wheels n rotating shafts n Oscillating shafts n Sliding shafts

3. Bearing loads

4. Axial or thrust load Radial Load Angular Load

5. Radial load

6. Angular load

7. Bearing Diagnosis n Normal bearing life n Bearing failure

8. Cylindrical Ball bearings n Radial loads only.. n Can be double rows of ball bearings.. n Installing bearing.. n Press the outer race in a housing.. n Press the inner race on a shaft..

9. HEAVY LOAD

10. Can be double rows of ball bearings n For heavy thrust loads n can with stand thrust loads

11. n Some FWD use a double tapered bearing.

12. Cylindrical Roller Bearings n Designed for Radial load n Can withstand some thrust load

13. Tapered roller bearings Excellent capability to handle : Radial Loads Thrust Loads Angular Loads

14. Adjustment

15. FWD

16. Springless seal

17. Double lip seal

18. Spring loaded Seal

19. Seal Replacement n Different brands look different n What is important is: n Match the OD n Match the ID n Some brands have a steel lip and some do not. n (Caution) The steel housing is very thin on some

20. Remember Not only does the seal need to look good now............ It need to be good enough for the next several thousand miles. Buying new seals are a cheap insurance
