The invention is a single-piece seal assembly comprising an annular seal body. A retainer is positioned at a first end of the seal body. A rotable seal is concentric with the retainer and has a notch positioned on an inner diameter of a first face of said rotable seal. In the notch is positioned a single shim. The shim is of a length such that it is capable of providing a selected seal compression. An annular bellows having first and second ends is affixed to an inner diameter of the seal body. On the first end of the bellows is a ring holder. The ring holder holds a ring seal.
