another potential IMS question...

Wikan,
The Micro Blue website is just marketing.About MicroBlue Polished And Coated Bearings
There is no comparison with the current best(?) standard:
"Ceramic Bearing Si3N4 ABEC-9 Stainless Steel "
If there was an independent comparison test ,that would answer your interesting question. Without this valid test data,it is just hype.
For comparison, you can find an Abec-7 ceramic bearing for $70.
S6204-2RS Bearing 20x47x14 Si3N4 Ceramic Stainless Steel Sealed Nylon ABEC-7 Ball Bearings VXB Brand: Deep Groove Ball Bearings: Amazon.com: Industrial & Scientific
Just remove 1 of the seals?

Don't go with the nylon cage, it won't last in the operating environment. There are steel cage silicon nitride bearings available.

you betcha no plastics or nylon allowed!!my tiptronic trans went out on a 03 986 boxster.175k miles. decided to do maintenance while waiting for replacement transmission, even though have never heard a peep out of the IMS.
Was amazed to find a 6204du bearing in it. 2 for 10 bucks on ebay. basically the bearing in my riding mower cutting deck!
read all I could stand on the ims replacements, and saw many wars from different people selling different things- roller, double in a single ceramic, OEM , spray oil thru it, all sorts of stuff. etc.
VXB has a 6204 double sealed ceramic with steel cage for 42 bucks, and someone's review there said excellent replacement for Porsche ims.
just kept searching and stumbled across the microblue site. ceramic deep groove, cryogenic frozen and heat treated. At 85 bucks figured is worth a look at one.
I think almost anything would be better than a Poland 6204du!
It looks like a neat idea, just wondered if anyone out there has ever seen one...
