In Reply to: Bearing oil again.. posted by Jugi on April 15, 2007 at 14:05:37:
My favorite, because it actually dropped the noise floor (on my TT anyway) is the van den Hul Spindle Oil. It's doped with zirconium oxide crystals (extremely hard!) which act like micro ball-bearings to keep the metal surfaces apart.I bought it on a lark after reading about it on the vdH website, but not really expecting to hear any difference. Guess what?!!

If the entire bearing is ceramic (the shaft and the bearing wall), I would not recommend it. If the shaft and housing are metal but use a teflon or ceramic thrust pad at the bottom (or top, if it's an inverted bearing,) that would be OK.
The shaft (inner bearing) and outer bearing wall is metal, the thrust pad at the top (it is inverted) is teflon, and the ball is ceramic. The instructions for the table tell me to place the oil in the upper oil bath of the inner bearing where the ceramic ball will sit and let it run over so it drips down along the bearing wall into the lower oil bath. Then the outer bearing slips over the inner bearing.Pictures are are in the link below, just scroll down the page.
Sounds like it would work. I also see VdH offers another oil, the TLF Type II which may work as well.
Yes, I think that would be fine. Ceramic is very very hard and will push the zirconium out of the way, while with teflon, the zirconium just imbeds in it (my Studietto has a teflon thrust pad.)It's just that some TT's employ a nylon or plastic outer bearing, and that might suffer unwanted wear.
I'm also looking at Tufoil and Marvel Air Tool Oil.
