Ball Bearing Study- Steel Balls –vs- Ceramic Balls

2. FWM Project- Surface Surface Roughness: Ball Bearing Contact Surfaces
Raceway~ 3AA
Ball ~ AA
Ball Bearing Contact Surfaces
Surfaces are ground, honed and lapped.

3. FWM Project- Contact Generalized Hertz Contact Case Steel-Steel
Cermic-Steel

4. FWM Project- Friction, Wear, Contact Fatigue
Ball Bearings are referred to as “anti-friction” bearings because of the small amount of friction.
Discuss sources of friction and relative amounts (effect of lubrication)
Wear will not occur if there is proper lubrication
Discuss contact fatigue, Weibul charts and method to calculate the L10 life of ball bearings

5. FWM Project- Elastohydrodynamic Lubrication
Discuss the differences in the minimum film thickness required for each material (based on composite surface roughness)

6. FWM Project- Summary
Discuss the differences found between steel-steel and ceramic-steel contacts
Compare with industry test results
Make determinations on why the predictions do or do not match test results
