Look into air bearings - the spinning motion 'injects' a film of air 
into the gap between the rotating parts, no contact, just like a hovercraft.

Look into maglev trains - the electro magnetic effect of what is, in 
effect, an unwrapped motor, provides the separation between the fixed 
rail and the moving train (you must have heard about the crash in 
Germany in the last few months! Same effect is used in some small fans.
