Abstract: A spherical plain bearing includes an outer ring having a concave interior spherical surface, and an inner member having a convex exterior spherical surface. The inner member is pivotally disposed in the outer ring such that the inner member and the outer ring are angularly misalignable relative to one another. The spherical plain bearing includes an angular misalignment restraint system which includes an inner member restraint feature on the inner member and an outer ring restraint feature on the outer member. The first and second portions are spaced apart when the inner member and the outer ring are angularly misaligned relative to one another by less than a predetermined maximum angle θ, and come into abutment when the inner member and the outer ring are angularly misaligned relative to one another by angle θ. The abutment prevents any further relative angular misalignment of the inner member and the outer ring.

Abstract: A spherical plain bearing includes an outer ring and an inner ring that are each coaxial with a longitudinal axis of the bearing. The outer ring has a first axial outer ring end, a second axial outer ring end, and an interior spherical concave bearing surface extending therebetween. The inner ring has a first axial inner ring end, a second axial inner ring end, and an interior cylindrical bearing surface defining a bore and an exterior spherical convex bearing surface extending therebetween. The exterior spherical convex bearing surface is in interfacial sliding engagement with the interior spherical concave bearing surface. A plurality of circumferential lubrication grooves and one or more curved lubrication channels are in the exterior spherical convex bearing surface. The curved lubrication channels are positioned to intersect each of the circumferential lubrication grooves. A plurality of profiled annular lubrication grooves circumferentially extend into the interior cylindrical bearing surface.

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.
