Abstract
A seal assembly is undersized in relation to the bore in which it is installed to permit radial floating of the seal assembly within the bore to enable precise coaxial alignment between the seal assembly and shaft, despite misalignment between the axis of the shaft and the axis of the bore. A retaining ring urges a face seal of the seal assembly into static sealing engagement with the stepped face of the bore to prevent leakage of the fluid around the seal assembly.
