ow and there was once an off topic asking how small jets could be and i found this

Re: bearings
Hi jack_h -
The type of bearings depend om how fast your shaft will spin... Below 30k ~ 40k rpm then ordinary bearings would do, 40k ~ 80k then ceramic-hybrids with cage is ok. And over 80k then it´s cage less hybrids.
As for lube, a light oil/fuel mist is used...
