Abstract: A bearing for use between an outer member and an inner member that is movable relative to the outer member. The bearing includes a generally cylindrical plastic body having a plurality of undulations that form gradual radially inward and radially outward waves relative to a circular path. The undulations accommodate for thermal expansion of the plastic bearing relative to a metal housing and shaft.

Abstract: Thermally conductive electrically insulating compositions and structures and devices comprising such materials. In various embodiments, such materials comprise liquid crystal polymer and fillers, wherein the fillers comprise boron nitride and glass fiber. In various embodiments, the liquid crystal polymer is selected from the group consisting of semi-aromatic copolyesters, copolyamides, polyester-co-amides, and mixtures thereof.

Abstract: A sealing system includes a housing defining a bore having an internal surface. A rotatable shaft is rotatably disposed in the bore and includes an annular groove disposed in an exterior surface of the rotatable shaft. The annular groove includes a groove bottom and a pair of lateral sidewalls. A seal is formed as a cylindrical annular thermoplastic body having an axial length greater than an axial length of the annular groove and which is bent into a V-shaped cross-section and received in the annular groove so that opposite ends of the seal are disposed in opposite bottom corners of the annular groove. A peak portion of the V-shaped cross section extends radially outward of the annular groove and is engaged with the internal surface of the bore.

Abstract: A thrust washer includes an annular body with an aperture therein and having a first axial face and a second axial face, an outer diameter edge and an inner diameter edge extending between the first and second axial faces. At least one of the first and second axial faces includes a plurality of recessed grooves extending at least partially between the inner edge and the outer edge and defining un-recessed lands between the recessed grooves. The plurality of recessed grooves include a transition region transitioning to the lands and a scoop region separated from the transition region by a stepped wall portion extending between the scoop region and the tapered region. The recessed grooves can include directional symmetric bi-directional grooves for use in systems with rotation in both directions.

Abstract: A thrust washer includes an annular body with an aperture therein and having a first axial face and a second axial face, an outer diameter edge and an inner diameter edge extending between the first and second axial faces. At least one of the first and second axial or conical faces includes a plurality of recessed grooves extending at least partially between the inner edge and the outer edge and defining un-recessed lands between the recessed grooves. The plurality of recessed grooves defining an average groove width and the plurality of lands defining an average land width between the grooves, wherein a ratio of the groove width to the land width is in a range of 0.2 to 2. The plurality of recessed grooves include a convex lead in surface having a lead in radius.

Abstract: A seal system includes a housing defining a bore having an inner bore surface. A rotating shaft is rotatably received in the bore and includes a recessed annular groove. A seal body has an unassembled form having a ring shape, wherein in an assembled state the seal member is received in the annular groove of the rotating shaft with the seal member flipped with a first side surface facing radially inward toward the annular groove and a second side surface facing radially outward toward the bore, the first side surface along a cylindrical outer diameter surface being lifted off of a bottom surface of the annular groove so that the second side surface along the outer diameter surface engages the inner bore surface while the second side surface along an inner diameter surface is spaced from the inner bore surface.

Abstract: A method of installing a seal on a fuel injector includes installing a seal in a groove in an outer surface of the fuel injector. The seal is then clamped in a heated clamp portion at a temperature sufficient to soften a material of the seal to allow the material to flow into the seal groove. The seal is then cooled while being maintained in the clamped state to allow the heated material to set to a desired outer diameter size. The seal groove in the fuel injector may be provided with an extrusion zone into which the softened material of the seal is allowed to flow as the seal outer diameter is reduced to the desired diameter during the heating and clamping process.
