Roller bearing faults are a common fault type in machines. There are several condition monitoring handbooks which describe ways of detecting these faults by means of vibration measurements. Handbooks on neither condition monitoring nor vibration analysis usually mention real order derivatives or cyclostationary technique. These methods have rarely been applied to vibration analysis in industrial condition monitoring , although plenty of studies on both of them have been published. In this study, these methods are applied on the fault detection of a roller bearing.
