Abstract
A mechanism and method for deciding whether a bearing is faulty or not. The method is performed by a controller. The method includes obtaining a signal representing vibrations of the bearing. The vibrations are obtained during operation of the bearing. The method includes applying signal segmentation to the signal in at least two frequency bands in order to identify any shock pulse in the signal. The method includes deciding whether the bearing is faulty or not depending on whether or not the signal has any shock pulse.
