1. Inside Face: That surface of the inner case which faces the exterior of the lip-seal assembly.
2. Inside-Face Inner Diameter: The inner diameter of the inner case of a radial lip seal.
3. Lip Inner Diameter: The inner diameter of the seal lip, measured with the spring installed.
4. Outer-Case Inner Diameter: The inside, or smallest, diameter of the outer case on a lip-seal assembly.
5. Outside Face: The surface of the seal case which is perpendicular to the shaft axis and which is not in contact with the fluid being sealed off.
6. Seal Outer Diameter: The external diameter of a lip-seal assembly, which normally corresponds to the out diameter of the outer seal case. In a package-type mechanical face seal, the diameter which corresponds to the outside surface of the cup.
7. Seal Width: The over-all axial dimension of the lip-seal assembly. This normally corresponds to the axial width of the outer seal case.
8. Shaft Diameter: The outside diameter of the shaft at the axial location where the seal is mounted.
