Method and device for mounting shaft seals permitting eccentric motion

A device for housing seals between a bore and a shaft, in which the shaft and bore may be subject to radial eccentricity, comprising:

• a. an annular sealing case having a first end and a second end;
• b. a shaft sealing case having a first end and a second end;
• and
• c. a flexible sealing linkage axially and sealingly connecting the second end of the annular sealing case to the first end of the shaft sealing case;
• wherein, the annular sealing case is shaped to receive one or more seals to seal against an interior surface of the bore, and the shaft sealing case is shaped to receive one or more seals to seal against an exterior surface of the shaft, and the flexible sealing linkage provides sealing between the annular sealing case and the shaft sealing case and is translatable to accommodate radial eccentricity between the shaft and the bore while ensuring that the annular sealing case remains coaxial with the bore and the shaft sealing case remains coaxial with the shaft.
