Abstract
An annular seal for use in sliding or translating applications is provided. An annular can comprises a metallic material formed into a ring. One or more ribs are disposed about an inner surface or an outer surface wall of the ring where the ribs provide a sliding sealing surface smaller having a reduced contact area relative to the width of the ring wall. The sliding sealing surface provides a seal against one or more sliding members. The rib-wall structure forms a circular beam providing greater structural integrity to the seal than would otherwise be possible.
