An axial face seal is a v-ring with an outer metal case added to it. Like a v-ring, an axial face seal mounts directly on a shaft and seals axially against either the housing or the metal case of a shaft seal. By incorporating a metal case into an axial face seal, they are able to seal out heavier contaminants than a v-ring would be able to. Unlike a v-ring, an axial face seal is not completely elastic, as a result of the addition of the outer metal case. This means that each axial face seal is designed for a specific shaft diameter rather than a range of shaft diameters like a v-ring. As was the case with v-rings, an axial face seal can either be used in conjunction with a shaft seal to provide additional contamination exclusion or they can be used by themselves in an application. The AFX style axial face seal is similar to the AFS except that the O.D. edge of the metal case extends beyond the rubber sealing lip. Because the metal case extends beyond the sealing lip, a groove needs to be machined into the housing to accept the metal case. In applications where heavy contamination is a concern, an AFX style seal would be better than an AFS because with the metal case extending into the housing there is a labyrinth created. By incorporating a labyrinth into the application the AFX will slow down the migration of the contaminants better than an AFS which will lead to longer seal life.
