[NSRCA-discussion] Ceramic Bearings

[ronlock at comcast.net]

I tried Ceramic bearings from Boca several years ago in an OS 1.40rx, running
in typical pattern set up, around 7,800.
As I recall, at only 30 flights or so they got rough.
Don't know how that may apply to current day ceramics.

Does anyone have any experience with ceramic bearings, specifically, Si3N4 silicon nitride, in a glow application?? I have been using sealed Stainless Steel in my OS160’s with pretty good luck. The ceramics are a bit more expensive but the stated properties are pretty attractive in our environment; very high temperature, low mass, totally corrosion resistant, reduced friction, etc…… Any input would be appreciated.
