ITEM NAME:   BEARING,WASHER,THRU
DEFINITION:  An item of any peripheral shape usually having one flat or spherical
             surface and a centrally located hole. It is designed for applications
             involving moving (kinetic) loads. Except for items fabricated from
             bearing quality synthetic (plastic) or composed of multilayer
             material, one bearing surface must either have a specific surface
             finish designation of 32 microinch (0.8 micrometre) or less,
             arithmetical average (aa) (arithmetic mean deviation) or one of the
             following conditions: be lapped or ground; have visible or detectable
             means of lubrication; grooves, indentations; or self-lubrication. The
             thickness must not exceed 25 percent of the outside diameter of the
             shortest distance between peripheral flats (when thickness and/or
             outside diameter is designated as a tolerance dimension, the maximum
             dimension will be used to determine compliance). Excludes straight,
             tubular (without flange) items having a bearing surface(s) parallel to
             the axis of the bore only. See also WASHER, FLAT and SPACER, SLEEVE.
