A condition monitoring with measurement of acoustic emission (AE) is effective in detection of rolling bearing failures. The AE which frequency bandwidth is from 50 kHz to 400 kHz is sensitive to propagations of rolling contact fatigue crack below or on raceway surface. However, there is no precedent which analyze relationship its sensitivity to parameters of the rolling contact fatigue failure quantitatively. In this research, we measured AE caused by rolling contact fatigue and repetition of one-point loading. The latter was a static approach to induce AE without interactions between the raceway surfaces and the ball set. We tried to discriminate surface factors for AE generation from subsurface factors by a combination of the dynamic and the static approach.
