  • Patent number: 6095690
    Abstract: Plain bearing elements comprise at least one single-layer metallic bearing material (4) having a sliding surface (6) with lubricating oil pockets (10). The depth (T) of the open oil pockets (10) is 0.03 mm to 0.3 mm, and the ratio of the pocket area to the pocket depth is 10 to 40 mm. The plain bearing elements exhibit superior running qualities and properties. The depth of the oil pockets (10) may be adapted to the service viscosity of the lubricating oil. The oil pockets (10) in the same plain bearing element may also have varying depths (T) and be provided only in predetermined regions of the plain bearing element.

  • Patent number: 4693617
    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.
