4320-12-331-9929 4320123319929 123319929 is a positive displacement device which utilzes the rotating motion of one or more gears, cams, vanes, or screws in an enclosure as a means of transferring a liquid from one place to another. it is designed to be driven manually or by a prime mover which is not an integral part of the pump. excludes aircraft engine pumps.

5365-14-206-7053 5365142067053 142067053 is a tubular shaped item with a round or hexagon peripheral shape having two flat bearing surfaces perpendicular to the axis of the centrally located hole. it is designed to maintain a predetermined distance between assembled parts. the item may be with or without flange(s) of any peripheral shape. the overall length must exceed 25 percent of the outside diameter or distance across peripheral flats of the body. (when the length, outside diameter, and/or distance across peripheral flats are designed as a tolerance, the maximum dimension will be used to determine compliance). for items having other than a round or hexagon peripheral shape, see spacer, plate. excludes items with lubricating features, see bearing, sleeve and bushing, sleeve. see also bushing, tapered; spacer, ring; washer, flat; and washer, (as modified).

5365-14-206-6583 5365142066583 142066583 is a flat metal or plastic item of various peripheral shapes having a solid (not laminated) cross-section. it is designed to maintain a predetermined distance between two surfaces. for round items without a hole having a solid rectangular cross-section use disk, solid, plain. for round or hexagonal items with only one hole centrally located and with the length (thickness) exceeding 25 percent of the outside diameter or distance across peripheral flats, see spacer, sleeve. the thickness between the two parallel bearing surfaces must be 0.006 inch, (0.152 mm) or more for items less than 1/4 inch (6.35 mm) across the peripheral diameter, or smallest overall outside dimension, or must be 0.016 inch (0.406 mm) or more for items 1/4 inch (6.35 mm) or greater across the peripheral diameter or smallest overall outside dimension. for items with a thickness less than those indicated above, see shim. for items with one hole centrally located conforming to the above dimensional criteria use washer, flat or spacer, ring as applicable. when thickness and/or outside diameter or smallest overall outside dimension is designated as a tolerance/dimension the maximum dimension will be used to determine compliance. excludes gasket&#59; insulator (as modified) and mounting pad, electrical-electronic component.
