Beschreibung
Zusammenfassung:	A sealing device may comprise: a flange that extends perpendicularly relative to a central axis of first portion; an inner cylindrical portion having an engaging surface, and a protruding portion extending between the flange and the inner cylindrical portion; a rigid body component; and an elastic component having a main oil lip and an excluder lip, wherein the main oil lip is proximate to or in contact with the flange at a first location, and wherein a the excluder lip contacts the inner cylindrical portion; wherein a gap is defined by surfaces of the first portion and the elastic component between the first location and the second location, and wherein, when the sealing device is installed in a bore so that the engaging surface is fixedly connected to the shaft and a machine is operated so that the shaft rotates, the volume of the gap changes by less than 10%.
