A couple of easy ways.


First the MI- number for a ball bearing head and an air head are  
different.  You can look in the book or a catalog sheet.


Second, try to rotate the head by hand.  If if will turn with out  any 
strength required, then it is a ball bearing head.  If it resist at  all do not 
force.


As far as I know, most would be air bearing.  You can use a regular  
compressor if you do a lot of filtering and water trapping.  Make sure  that the 
filter gets all oil and is down to certain micron size.  Maybe  someone has 
those specs.

Hope  you've got an oil-free air compressor system for the head's  
air-bearings...  
or does it have a ball-bearing head?
