3120-17-123-2192 3120171232192 171232192 is 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.

4130-00-123-2192 4130001232192 001232192 is a replaceable device designed to remove dust, pollen or other foreign matter from the air passing through it. the removal of particles is accomplished by porous fibrous or shredded material (metallic or nonmetallic) which is loosely woven or matted and confined in a frame or retained between perforated sheets of firmer material. it is designed to fit into air conditioners, ventilation systems and hot air furnaces. it may have facilities for radio frequency/electromagnetic interference shielding. the filter may be cleaned by the use of compressed air, blown through the filter element, or by using water and a suitable detergent for cleaning purposes which would extend the life of the filter.
