ITEM NAME   BEARING,ROLLER,AIRF
DEFINITION  A cylindrical item in which the inner or outer ring turns upon row(s)
             of hardened ROLLER, BEARING which roll on a raceway, thus minimizing
             friction. These items are characterized by their noncorrosive
             qualities, lightness of weight, inch dimensions rather than metric,
             inner rings generally projecting beyond the faces of the outer ring,
             or a very narrow width inner ring having an outside diameter slightly
             larger than the bore diameter. Designed primarily for use in aircraft
             assemblies, such as control systems and surfaces of aircraft. Excludes
             BEARING, ROLLER, CYLINDRICAL.
