A tubular shaped item with or without flange(s) designed to reduce friction and carry a kinetic load on the surface(s) parallel to the axis of the bore. It must have a visible or detectable means of lubrication or be self-lubricated. The over all length must exceed 25 percent of the outside diameter or the shortest distance between peripheral flats of the body, except for straight tubular (without flange or shoulder) items having a bearing surface(s) parallel to the axis of the bore only. Includes items which are divided into two or more segments which include 180 degrees (3.141 radians) or less of the bearing periphery. See also bushing, sleeve; spacer, sleeve; and washer (as modified). Excludes:pin, hollow.
