I was part of one of those earlier posts and I finally found the seal that works on the outside as Trauschu seems also to have. It ended up as a Federal Mogul 2148.

I fully understand and appreciate FBody's concern but I had NO machined area on one side to put a seal inboard, and the other side looked suspect.

I have the same setup now Trauschu, Timken style bearing, seal, plate. The seal looks reasonably heavy to take lateral forces, but will certainly monitor everything on a maintenance regime.
