A Review of Rolling Contact Fatigue

6 The phenomenon of RCF occurs in a very small volume of stressed material because the contact stress eld is highly localized Typical bearing contact widths are of the order of 2001000 m 7 The evolution of RCF damage leading to a fatigue spall involves a threestage process i shakedown ii steadystate elastic response and iii

Sand Separators In some applications where the water contains a large amount of sand a sand separator may be required Figure 3 Sand separators swirl the water using centrifugal action to separate sand and other heavy particles from the water Properly functioning sand separators can remove 70 to 95 of heavy particles with equivalent diameters
