Abstract
Floating seal assemblies having a seal element, a support band, and at least two loading springs that produce different spring forces to apply different sealing loads at the first and second sealing flanges of the seal element. The seal assembly is without a locking ring to enable the seal assembly to float along an axis of one of the components to be sealed. The different sealing loads allow the seal assembly to grip against one surface to prevent relative rotation and to enable sealing and relative rotation with another surface.
