This causes a spall, or the liberation of a small section of bearing surface material.
The same process can be occurred earlier than expected in the event that any of the failure mechanism described in the previous paragraph produce a surface or subsurface defect which is large enough to significantly increase the surface and subsurface stresses at the bearing materials.
These cracks may cause surface fragments of bearing material to break away.
