Abstract:
A self-adjusting seal for sealing a joint. The joint includes a support member, a mis-alignable component, and a changeable gap between the support member and the mis-alignable component. The seal includes a first part having a generally annular configuration formed of a resiliently crushable material and defining a planar outer seal face to statically seal to the support member and a first seal part opening extending therethrough. A second seal part axially adjoins the first part. The second seal part has a generally annular configuration formed of a rigid material and a second seal part opening extending therethrough in axial alignment with the first seal part opening. The first and second seal part openings define a non-rotation feature to prevent rotation of the seal on the support member, the second seal part defining a planer inner seal face configured to dynamically and sealingly interface with the mis-alignable component.
