Abstract
A device and method are taught for mounting an annular shaft seal between a bore and a shaft in which the shaft and bore may be subject to radial eccentricity. The device comprises an annular sealing case having a first end and a second end; a shaft sealing case having a first end and a second end; 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. The annular sealing case is shaped to receive a seal to seal against an interior surface of the bore, and the shaft sealing case is shaped to receive a seal 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.
