Abstract: An axial retainment system for a shaft is provided. The axial retainment system includes a cylindrical body extending from an outboard end to an inboard end thereof, and a swaged ridge extending radially outward from the cylindrical body proximate the outboard end. The swaged ridge has an outboard axial surface facing toward the outboard end and extending radially outward and terminating at a radially outward facing circumferential surface. The swaged ridge has an inboard axial surface facing toward the inboard end and extending radially outward from the cylindrical body and terminating at the radially outward facing circumferential surface. The outboard axial surface of the swaged ridge is recessed axially inward from the outboard end of the shaft. The inboard axial surface of the swaged ridge is swaged against, conforms in shape to, and is compressed against a component to be axially retained on the shaft.

Abstract: A maintenance-free bearing system having self-lubricating features, seals, grooves and slots for use in a cushion hitch assembly for a hitch pull scraper vehicle. An interconnected bearing linkage system having two or more horizontal two-axis combined journal and thrust bearings with self-lubricating liners therein, two or more vertical single-axis sleeve bearings with self-lubricating liners therein and one or more vertical thrust bearing with self-lubricating liners therein, that cooperate with one another to accommodate vertical and horizontal angular movement relative to one another. The vertical thrust bearings incorporate an outer seal assembly and/or an inner seal assembly with a tapered configuration that improves retention of the seal assembly during rotation.

Abstract: A railway switch system includes a base plate that has an exterior surface and a movable elongate rail that has a mounting flange that has an exterior surface that faces the exterior surface of the base plate. The railway switch system includes a lubricious liner disposed between the base plate and the mounting flange and mounted in parallel engagement on top of a substrate that is one of: the exterior surface of the base plate, the exterior surface of the mounting flange, and an exterior surface of an intervening plate disposed between the base plate and the mounting flange. The lubricious liner has an exposed bearing surface, has a second width, extends continuously across the second width, and is substantially planar. The lubricious liner consists of a non-metallic graphite free material consisting of a blend of polymer resin, fibers and a lubricant.

Abstract: A spherical bearing includes an inner member that has an exterior surface extending a first width between axial ends thereof and having a first central plane located equidistant between the axial ends. The spherical bearing includes an outer member with a inner surface having a maximum inside diameter at an apex plane and extending a second width between opposing ends thereof and having second central plane located equidistant between the ends thereof. The inner member is disposed in an interior area of the outer member. The first central plane is coplanar with the apex plane and is axially offset from the second central plane. One of the opposing axial ends of the inner member is located entirely in the interior area and axially inward from ends of the outer member when the inner member is angularly misaligned relative to the outer member at non-zero angles up to 7 degrees.

Abstract: A bushing for a stator vane assembly of a gas turbine engine has a tubular member that is coaxial about a longitudinal axis and that extends a length between a first axial end and a second axial end. The tubular member has an outside circumferential surface thereon and an inside circumferential surface therein and is manufactured from a cobalt based alloy, a nickel based alloy, a graphite material, a cermet material or an alloy matrix comprising titanium, aluminum, niobium, manganese, boron, and carbon and a solid lubricant being dispersed in the alloy matrix. A portion of the inside circumferential surface and/or a portion of the outside circumferential surface has a wear resistant material thereon.

Abstract: A bearing assembly includes an outer race having an inner surface defining a concave contour and an inner race positioned in the outer race. The inner race has an inner surface defining a bore therethrough and an outer surface defining at least one groove circumscribing the outer surface. A plurality of rolling elements is rollably located in the groove and is in rolling contact with the inner surface of the outer race. A lubricious liner has an inner liner-surface and an exterior liner-surface, the exterior liner-surface being disposed on the inner surface defining the bore. The lubricious liner has a modulus of compression of a magnitude sufficient to allow misalignment of the inner liner-surface relative to the exterior liner-surface in response to a force applied thereto.

Abstract: A sleeve for a valve assembly has an annular body with an inside surface extending from a first axial sleeve-end to a second axial sleeve-end. The inside surface has a first cylindrical section and a second cylindrical section with a conical interior seating surface extending therebetween. A groove extends circumferentially around and radially outward in the first cylindrical section and axially away from the conical interior seating surface towards the first axial sleeve-end. The sleeve includes one or more first ports that extend radially through the first cylindrical section and spaced apart from the groove. The one or more first ports are spaced apart from the groove by a lip formed by the first cylindrical section. The lip extends continuously and entirely circumferentially around the first cylindrical surface and extends a predetermined axial distance between the groove and the one or more first ports.

Abstract: An axial retainment system for a shaft is provided. The axial retainment system includes a cylindrical body extending from an outboard end to an inboard end thereof, and a swaged ridge extending radially outward from the cylindrical body proximate the outboard end. The swaged ridge has an outboard axial surface facing toward the outboard end and extending radially outward and terminating at a radially outward facing circumferential surface. The swaged ridge has an inboard axial surface facing toward the inboard end and extending radially outward from the cylindrical body and terminating at the radially outward facing circumferential surface. The outboard axial surface of the swaged ridge is recessed axially inward from the outboard end of the shaft. The inboard axial surface of the swaged ridge is swaged against, conforms in shape to, and is compressed against a component to be axially retained on the shaft.

Abstract: A bearing includes an outer ring with a first outer roller race, a second outer roller race, and a radially inward facing outer ball race. The bearing includes a first and second inner rings that axially abutting one another at an abutment interface. The first inner ring has a first inner roller race, the second inner ring has a second inner roller race that are disposed in an interior area coaxially with the outer ring. A plurality of first rollers rollingly engage the first outer roller race and the first inner roller race. A plurality of second rollers rollingly engage the second outer roller race and the second inner roller race. A plurality of balls rollingly engage the outer ball race and the inner ball race.

Abstract: A piston assembly including a shaft having a piston arrangement. The piston arrangement has a retract-area on one side and a extend-area on the opposite side. The retract-area is larger than the extend-area so that when fluid exerts a force on the retract-area the piston arrangement generates and applies a retract force to the shaft. Upon release of the fluid pressure to the retract-area and application of the fluid pressure to the extend-area the piston arrangement generates and applies an extend force to the shaft. The retract force is greater than or equal to the extend force.
