Once the cage starts to lose its integrity friction increases even more leading to total disintegration of the cage. This results in the two steel races and ball bearings remain pretty much intact (although damaged), however the cage disintegrates into pieces. Because the balls are no longer properly spaced within the inner and outer races, the two races separate leading to catastrophic failure of the bearing. In IMS failures the debris is carried throughout the engine causing even more damage.
