A significant development in condition monitoring techniques has been observed over the
years. The scope of condition monitoring has been shifted from defect identification to its …

Subsurface mesoscale cracks exist widely in the outer ring of full ceramic ball bearings
(FCBBs), which is a potential threat for the stable operation of related devices such as aero …

Background Tunable Q-factor wavelet transform (TQWT) is a newly developed, updated
version of the wavelet transform that can break down any vibration signal into low Q-factor …

Considering the effect of ball diameter difference, the full ceramic ball bearings often run in
uneven loading conditions in starved lubrication. The uneven loading condition leads to …

During the degradation of critical rotating components using ceramic materials, due to the
uncertainty of the failure generation mechanism, the high nonlinearity of failure evolution …

Distributed defects in rolling element bearing arise due to the progression of small localized
pits. If not monitored on time, this leads to premature or may turn into catastrophic failure of a …

Rotating machine is a common class of machinery in most of the industry and the main root
cause of machinery failure is a faulty bearing. Bearings are most widely used in various …

As slewing bearings in wind turbines are exposed to complex operational environments,
they are prone to crack initiation, propagation and evolution that can lead to contact fatigue …

Rolling bearing elements develop structural changes during rolling contact fatigue (RCF)
along with the non-proportional stress histories, evolved residual stresses and extensive …

Abstract The surface-initiated Rolling Contact Fatigue (RCF) including pitting and micro-
pitting is one of the key issues affecting the reliability of tribological components such as …
