Dev Roller replacement

Does anyone know the life on these dev rollers and what problems they might cause when they start to go.

If you mean the mag roller in the developer unit, they are rated to 480k but i've seen them last 800k. When they start to go, they will cause background along the top and sometimes bottom edge of the image. If the magnet is loose, a ring of developer will buildup in the center of the tapper bar under the mag role.

I have some machines that have over a million and still have the original rollers.I come from a Canon background and they were call dev rollers....sorry.All the Canon Black and Whites were mono component and produced different problems when they got old.
