Abstract: A plain bearing includes a metal outer ring having an inner surface and a metal inner ring having an outer surface configured to cooperate with the inner surface of the outer ring to permit relative movement of the inner and outer rings. At least the outer surface of the inner ring is provided with a plasma electrolytic oxidation coating and/or at least the inner surface of the outer ring is provided with a plasma electrolytic oxidation coating.

Abstract: A plain bearing includes an outer ring having an inner surface and an inner ring having an outer surface in contact with the inner surface of the outer ring. The inner ring is configured to cooperate with the outer ring to permit relative movement, and the inner ring or the outer ring or the inner ring and the outer ring is made of a metal matrix composite material.

Abstract: A bearing liner includes a binder with a resin material, a pre-preg, a structural yarn and a lubricating yarn, and particles of aluminum oxide (Al2O3). The particles of aluminum oxide may be embedded within the binder or within the lubricating yarn, or may be embedded within both the binder and the lubricating yarn. A plain bearing includes an inner ring, an outer ring and such a liner interposed or disposed between the rings.

Abstract: Plain bearing providing an outer ring with an inner surface, an inner ring with an outer surface, the rings being symmetrical around an axis and metallic, at least on the rings being a textured ring with a texturation consisting of a plurality of micro-cavities arranged onto a textured surface. A composite self-lubricating composite liner that is interposed between the inner surface of the outer ring and the outer surface of the inner ring, so that upon sliding movement of the textured ring with respect to the composite liner, some solid particles of the liner, acting as a solid lubricant, are detached from the composite liner and migrate between the sliding surfaces until they get retained into the micro-cavities.

Abstract: A bearing liner includes a first fabric having a fiber sheet pre-impregnated with a binder. A second fabric is impregnated with the binder and has a bearing element contact surface with lubricating fibers and structural fibers supporting the bearing element contact surface. The fiber sheet and the binder incorporate electrically conductive fillers.

Abstract: A bearing assembly is for movably coupling first and second members, one being movable relative to the other. A plain bearing section includes an inner ring connectable with the first member and an outer convex bearing surface. An outer ring is disposed about the inner ring and has an inner concave bearing surface disposed against the inner ring bearing surface. The two bearing surfaces are formed such that one bearing surfaces slides against the other when the movable member displaces about a first axis and two bearing surfaces engage to prevent displacement between the two rings when the movable member displaces about a second axis. An elastomeric bearing section is disposed about the plain bearing section, is connected with the second member and formed such that at least a portion of the elastomeric bearing section flexes when the movable member angularly displaces about the second axis.

Abstract: A bearing assembly is for movably coupling first and second members, one being movable relative to the other. A plain bearing section includes an inner ring having a bore for receiving the first member and an outer cylindrical bearing surface. An outer ring is disposed about the inner ring and has an inner cylindrical bearing surface disposed against the inner ring bearing surface, one bearing surface sliding against the other when the movable member displaces about a first axis. The two rings engage to prevent relative displacement between the rings when the movable member displaces about a second axis. An elastomeric bearing section is disposed about the plain bearing section, is connected with the second member and is formed such that at least a portion of the elastomeric bearing section flexes when the movable member angularly displaces about the second axis.
