N2 - This paper analyses the vibrations emitted by a set of grease lubricated ball bearings run under load, when lubrication conditions alternate between good and insufficient. Conditions are varied by adjusting the operational parameters rotational speed and temperature. The dependency of the vibration signature on the lubrication ratio κ is considered. The results show a good correlation between κ and spectral kurtosis for a given frequency band, a: when the bearing is new, and b: when κ is below 0.6.
