That seal and the SKF/CR 6904 are the closest non-OEM matches that I know of so far.  I have used both on my saws.  They are tighter on the shaft than the OEM 530019075 seals.  Makes instalation a bit tricky on the PTO side because of the pronounced step on the shaft.

I have ruined two of them during instalation onthe PTO side.  Rolled the lip and ejected the garter spring.  May also shorten the life of the seals (I have had no failures so far, but haven't put many hours on them yet).  Tim (Fossil) was working on finding a better match.  I can't remember how far he got.  He's very resourceful.
