The bearing includes a convex outer surface having a hemispherical surface, a curved lead-in surface, a flat flange surface, a curved relief surface, and a flat tapered surface. The curved relief surface extends inward relative to the flat tapered surface, and the flat flange surface extends outward relative to the flat tapered surface. The shell component includes a concave inner surface having a tapered surface configured to engage the tapered surface of the bearing. An annular groove is defined in the concave inner wall of the shell component and is configured to receive the flat flange surface. Methods for assembling and using the prosthetic implant are also disclosed.
