Abstract It is known that supported ball bearings have great effects on the vibrations of gear transmission system, above in all presence local faults as well crack growths. For this purpose, paper focuses shock and vibration growth diagnostic bearing using analysis. Our work devoted first to a study static behaviour by determining stress, strain displacement, then its dynamic four natural freq...

Bearing steel under severe loading condition undergoes substantial subsurface microstructural alterations known as Dark etching regions and white bands. White bands (WEBs) develop after hundreds of millions stress cycles in bearing components have been reported for several decades but the formation mechanism is not fully elucidated. Current research presents a systematic rolling contact fatigue...
