RB 9RB Axial Face Seals Gamma Seal Ring
An axial face sea (gamma 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-ing would be able to. Unlike a V-ring, an axial face sea 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.
Pinmo offer two standard axial face seal styles. The two styles that are offered are RB and 9RB (AFS and AFX, Vrm01 and Vrm02).
The RB style axial face seal is the industry standard for face seals. An RB style axial rubber sealing lip. Therefore, when an RB style seal is installed into an application there is a narrow gap between the edge of the metal case and the housing. RB style seals are offered for shaft diameters ranging from 10 mm to 135 mm.
The 9RB style axial face seal is similar to the RB 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 application where heavy contamination is a consern, an 9RB style seal would be better than an RB because with the metal case extending into the housing there is a labyrinth created. By incorporating a labyrinth into the application the 9RB longer seal life. 9RB style seals are offered for shaft diameters ranging from 10 mm to 135 mm.
