If the thrust or journal bearings become excessively worn, then they can cause damage to the seal plates like in the example pictured here.

Here, the seal plate has been damaged by excessive play in the journal bearings (also known as thrust bearings).

In this image, you can see a seal plate with the tell-tale signs of corrosion damage. On a new, undamaged back plate, the surface would be smooth, but here, corrosion has caused the face of the seal to become pitted, worn and roughened.
