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

<P class=MsoNormal>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.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></P>
