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?
