Spindles of WHAT? Milling machine, lathe, router?

Or, are you talking about high-speed air bearing spindle motors? These
are special
bearings where AIR is used as the lubricating film. The advantage is
the friction
is minute, so they don't need to be cooled like an oil-film bearing
would be at
100,000 RPM.

You need to give us more background on what you are interested in to get
a better
answer.
