Zusammenfassung:	The present invention provides a dynamic seal for enclosing a radial gap between coaxial, relatively rotatable inner and outer members. The dynamic seal includes an inner seal part, mountable to the inner member; an outer seal part, mountable to the outer member; and a counterface part radially suspended between the inner and outer seal parts and coaxial therewith. Each of the inner and outer seal parts provides a set of first and second sealing elements, which bear against oppositely oriented axial surfaces of the counterface part. The counterface part is thus axially retained in both directions by the inner seal part at a radially inner contact location, and is axially retained in both directions by the outer seal part at a radially outer contact location.
