Abstract
Two seal elements are respectively mounted on generally coaxial relatively rotatable members so that each seal element is capable of relative radial movment with respect to its associated member. One of the seal elements is mounted on its associated member in such a manner that they remain coaxial. The seal elements have confronting radially spaced apart surfaces which are so configured that together they define a hydrodynamic gas bearing. The arrangement is such that upon the relative rotation of the members said seal element which is mounted so as to remain coaxial with its associated member hydrodynamically supports the other seal element so that they remain coaxial.
