Deflection compensation roll

An apparatus comprising:

• a non-rotating carrier;
• a rotatable jacket arranged to rotate around said non-rotating carrier;
• a sealing device arranged between said non-rotating carrier and said rotating jacket to separate an inner atmosphere of the apparatus from an outer atmosphere of the apparatus;
• said sealing device comprising a ring groove having a side wall arranged adjacent to the outside atmosphere of the apparatus and a radially movable ring body, positioned within said ring groove, having a circumferential surface;
• an axial sealing lip coupled to an axial surface of said ring body that is located adjacent to said side wall, the axial sealing lip being arranged to move with said ring body;
• and
• a radial sealing lip coupled to said circumferential surface of said ring body.

A deflection compensation roll with a jacket lift, comprising:

• a carrier;
• a support device coupled to the carrier;
• a jacket rotatably mounted on the support device;
• at least one radial seal and at least one axial seal being positioned between the jacket and the carrier;
• a ring groove comprising at least one side wall and being coupled to one of the jacket and the carrier;
• a ring body arranged for radial movement in the ring groove, the ring body comprising at least one axial face and a circumference;
• the circumference of the ring body comprising one of an inside circumference and an outside circumference;
• the ring body being secured against rotation relative to the ring groove;
• a cylindrical sealing surface adapted to engage the circumference of the ring body coupled to the other of the jacket and the carrier;
• an axial sealing lip disposed between the axial face and the at least one side wall of the ring groove;
• and
• a radial sealing lip located on the circumference of the ring body,
• wherein the radial sealing lip rotates relative to the cylindrical sealing surface.
