Ideally, rolling bearing elements are separated by a protective lubricant film, which impedes their collision. However, manufacturing defects, damages, which appear during operation, dirt in the bearing, insufficient or incorrect lubrication – all these factors cause the collision of the bearing elements and, as a result, acoustic oscillations of a wide spectrum are generated in the bearing body.
