Wear of rolling bearings: signs, causes and remedies - Engineer …

14/4/2015· Abrasive wear of rolling bearings, often referred to as ‘three-element’ wear, is the removal of material from three main areas of a rolling bearing: the raceways, the end faces of the rolling elements, and the ribs/cages. Abrasive wear normally takes the form of a high lustre (ie semi-glossy) finish with a mirror-like surface structure.
