Abstract

An assembly (20) includes a rotating seal land (30), a seal element (68), a stationary seal support (34) and a mating plate (82). The seal element (68) axially overlaps, circumscribes and radially sealingly engages the rotating seal land (30). The stationary seal support (34) axially overlaps and circumscribes the rotating seal land (30) and the seal element (68). The stationary seal support (34) includes a support notch (48), a support shoulder (50), a support inner interior surface (52) and a support outer interior surface (54). The support notch (48) projects axially into the stationary seal support (34) from a distal end (36) of the stationary seal support (34) to the support shoulder (50). The support notch (48) projects radially outward away from an axis (28) into the stationary seal support (34) from the support inner interior surface (52) to the support outer interior surface (54). The mating plate (82) is seated in the support notch (40) and mounted to the stationary seal support (34). The mating plate (82) axially contacts the support shoulder (50) and the seal element (68).
