While cleaning the place for visitors next week, I came across a bag
full of ceramic bearings, ie, bearings in races where the bearings
themselves are ceramic and the races seem to be teflon. I forget why
we bought them but for salt water apps, they'd be great. Supposedly do
not need lube. So, can anybody think of any apps for similar bearings?



Kaydon makes a bearing originally designed for aerospace applications.
They are subjected to a process called "Microsealing" that impregnates the
balls and bearing races with a proprietary dry lubricant that does not
outgas.
I believe the balls are ceramic. Designed for applications over 400 degrees
C
in a vacuum.

I used them in the planetary fixture systems in optical coating systems.
