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 AFS style axial face seal is the industry standard for face seals. An AFS style axial face seal is designed so that the O.D. edge of the metal case does not cover all of the rubber sealing lip. Therefore, when an AFS style seal is installed into an application there is a narrow gap between the edge of the metal case and the housing.
