Abstract: A device including a first axial portion, a second axial portion, and a radial portion is disclosed. A portion of the second axial portion is configured to connect to a hub. An upper surface of the second axial portion may be positioned above an upper surface of a sleeve limiter shoulder when the portion of the second axial portion is connected to the hub. The radial portion connects the first axial portion to the second axial portion. The radial portion is configured to increase stiffness by increasing surface contact between the radial portion and the sleeve limiter shoulder.
