  • Wear of rolling bearings signs causes and remedies

       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.
