Abstract: A linear guide mechanism includes a housing having an inside housing surface that defines a bore extending through the housing coaxial with a longitudinal axis. A shaft is disposed at least partially in the bore and is reciprocatably and linearly moveable in the bore along the longitudinal axis. The shaft has an exterior shaft surface. A self-lubricating liner is disposed in the bore between the inside housing surface and the exterior shaft surface. The self-lubricating liner has an inside liner surface that is in sliding engagement with the exterior shaft surface of the shaft. The self-lubricating liner has an exterior liner surface.

Abstract: A roller hydraulic valve lifter includes a body having a longitudinal central axis and an interior area defined by an inside surface which has a pair of flat surfaces opposite one another and connected by a pair of walls. A first bore, essentially perpendicular to the longitudinal axis, extends through the flat surfaces. A bearing is disposed partially in the interior area. The bearing includes an outer ring having substantially cylindrical exterior and interior bearing surfaces. A shaft extends through the first bore and the outer ring and between the pair of flat surfaces. A plurality of needle rollers is disposed between and rollingly engage the shaft and the cylindrical inner bearing surface. The shaft and the plurality of needle rollers are manufactured from an AISI 52100 alloy steel that is carbo-nitrided. The shaft and the plurality of needle rollers have a surface hardness of a minimum of HRc 65.

Abstract: An anti-wear composite structure includes an anti-wear layer that has a wear surface opposite an adhesive receiving surface and a thermosetting resin applied to the adhesive receiving surface. The thermosetting resin includes a reactive adhesive configured to bond the anti-wear composite structure to a substrate at an ambient temperature band via pressure-sensitive adhesion. The thermosetting resin has an onset to cure in the ambient temperature band and has a peak cure temperature greater than the ambient temperature band to mechanically and chemically bond the anti-wear composite structure to a substrate.

Abstract: A seal for a flexible alignment sealing coupling. The seal includes an annular member being symmetric about a longitudinal axis. The annular member has a radially inward facing surface extending an axial width between a first axial end and a second axial end. In a relaxed state of the seal, the radially inward facing surface has an asymmetric generally concave V-shaped cross section and is defined by a first section and a second section. The first section has a first seal taper angle measured relative to a line parallel to the longitudinal axis. The second section has a second seal taper angle measured relative to another line parallel to the longitudinal axis. The first seal taper angle is less than the second seal taper angle. Each of the first seal taper angle and the second seal taper angle is greater than zero degrees and less than 90 degrees.

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.
