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 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.

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.
