Abstract
A load ring for a seal assembly includes an inner axial surface, an outer axial surface, a first frustoconical surface, a second frustoconical surface, and a rib. The inner and outer axial surfaces are cylindrical and extend along a longitudinal axis. The outer axial surface is in outward radial relationship to the inner axial surface along a radial plane which is perpendicular to the longitudinal axis. The first and second frustoconical surfaces are annular and extend radially between the inner axial surface and the outer axial surface. The second frustoconical surface is in spaced relationship with respect to the first frustoconical surface along the longitudinal axis. The rib projects radially inwardly from the inner axial surface.
