Just a suggestion

Howe00 I agree with you about the rs is a grease seal and not intended to keep oil out just the grease in. I also agree the grease should be approx. 30%. But Porsche did not use a rs seal, the seal type is a DUA17. We know what the 6204 stands for. The BD20-17 on the bearing itself is a proprietary number used for Porsche designed bearing built by NSK. Its 2ea. 6204 bearings side by side with the innerside seal mounts removed from each bearing. That is why the odd size width deminsion of 23.75mm and isn't available.
Back to the seal, DUA17. Maybe you could help me out with your experience, could you find out what it exactly means?

It does not look or feel like the typical rubber seal. Any help there would be great.
