ABSTRACT:
A slider bearing assembly has a bearing housing having a bore centered on an axis and having an inside bore surface and a uniform composition plain bearing liner in and coaxial with the bore and having an outer surface delimited by two axially oppositely directed end faces, an axial middle region between the end faces, and an inner surface centered on the axis. The bore and outer surfaces are in mutual surface contact in a contact area and normally directly engage each other without the interposition of a liquid lubricant. The bearing liner is fixed in the housing against any movement relative thereto other than micromovements. A movable part has a journal centered on the axis and radially outwardly confronting and normally engaging the inner liner surface. This movable part is nonradially movable relative to the liner and housing, that is it can only move axially and/or angularly relative to the liner. Drainage channels formed in at least one of the surfaces at the contact area extend to the axial end faces. The liner is of uniform radial thickness at least between the channels. Lubricant is withdrawn from the channels to maintain the contact area substantially dry.
