heal.abstract	Although vibration analysis has been established as an effective condition monitoring for rolling element bearings, significant practical problems still appear. A frequently encountered industrial case for example, is the separation of vibration responses of the same type of bearings inside the same machine, mounted for e.g. on the same shaft. In this case, methods for the decomposition of the measured signals into a number of independent components are quite important, so that the individual bearing sources can be analyzed separately. However, only recently BSS approaches have been applied for rotating machinery failure detection. The objective of this paper is to examine the efficiency and the performance of a series of well-known BSS algorithms in separating the vibration responses of the same type of rolling element bearings under the same operating conditions.	en
