Default Ceramic Ball Bearings

I've just got at a very cheap price a complete kit of ceramic ball bearings for my RRR. http://www.planetracing.it/cuscinett...sho-p-439.html

How they must be lubricated? Oil or grease?

I noted that they have one side metal shielded and the other one rubber shielded. Which are the differences? Theoretically speaking I would say that metal shielding gives less friction but rubber shielding gives more protection from the dust. Anyone has experienced in the use of ceramic balls bearings?

"oil is generally the bearing lubricant of choice on those applications where higher speeds and operating temperatures are expected." " Heavier load and higher temp, higher oil viscosity" " If operating temperature is low or speed is high, low viscosity is needed." Need high quality non-oxidizing mineral oil or synthetic oil. Ceramic is heat resistant.

Since this is small and fast go very light; perhaps lube from a skateboard shop. Use a light amount.
Yeah, rubber seals are slightly more resistant, but the metal shields get dirtier.
