Spalled Bearings - Machinery Lubriion

If the bearing is removed from service soon after the macropitting started, surface damage will be evident on only a sector of the IR. The case history also describes a broken cage. This usually occurs in tapered-roller bearings when they have excessive clearance, when axial loads reverse quickly, or when debris from a failure lodges between a roller and the cage.
