An accurate method to calculate bearing defect length allows quantitative determination of defect severity. With defect size and progression of development known, remaining bearing life can be estimatedSHEPPARDHydrocarbon ...
As a consequence, experimental tests on the vibration of cylindrical roller bearings with a single square defect measuring 1mm by 1mm on their inner race and rolling element were conducted, and the findings were presented and analyzed. In this investigation, only square defects were created and ...
Consistent with this hypothesis, we confirm that zebrafish CFAP20 functions in tissues bearing motile cilia, and plays an essential role in photoreceptor outer segments (i.e., non-motile cilia). InC. elegans, CFAP20 is required for the structural integrity of the inner junction and, similar to...
In this paper, the dynamic behavior of a rotor-bearing-SFD system with the inner race defect of bearing is investigated. The contact force between the rolling element and the race is calculated in Hertzian contact and elastohydrodynamic lubrication condition. The supporting force of the SFD is ...

Hence, it is necessary to estimate the severity of the defect. For bearings, a common failure mechanism is spalling in the raceways. The objective of this study was to estimate the spall width located on the bearing inner race by analysis of its vibration signature. This study broadens ...
