Milimetr, I'm glad you mentioned the matter of non-metallic bearing materials. You must not use the VDH Spindle Oil with assemblies containing plastic, Delrin, Nylon or Teflon parts, due to excessive wear AND the fact that the hard zirconium oxide particles will become embedded in those soft materials and essentially lose their effectiveness.
I'm not familiar with the Raven AC or its bearings' specifications; however, the platter on my Goldmund is not that heavy, and yet it still takes a long time to settle down, regardless of the oil used. I'm sure being a Goldmund product, the spindle bearing is manufactured to tight tolerances but I see no danger in using the VDH zirconium-doped product. In fact, I would think the product would be even more effective in a belt-drive TT, to reduce the effect of asymmetical loading on the spindle bearing.
