Patent number: 11686343Abstract: 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.Type: GrantFiled: October 19, 2021Date of Patent: June 27, 2023Assignee: Roller Bearing Company of America, Inc.Inventors: James Voisine, Bradley Smith
