Paper Polished Shaft Surface Finish for Radial Lip Seals 930534

In recent years, the methods for finishing shaft surfaces for radial lip seals have received greater attention.

Each finishing process requires its own specification. This paper evaluates paper-polishing for preparation of radial lip seal running surface finishes.
