Metric Oil Seals Style MOS
A shaft seal is a barrier with four functions. It retains lubricants or liquids, excludes contaminants, separates fluids and confines pressure. Essentially, they consist of a rubber sealing lip, a stiffening metal core, and a garter spring. Depending on the application. There are three standard Lip types: A, B,and C. See exploded image of ADL style below. Type A The rubber elastomer outer covering tolerates thermal expansion as well as roughness in the housing bore. There will be no fretting corrosion. Damage to the housing bore will be prevented when frequently replacing the seal. This type qualifies for sealing gaseous or liquid media. Type B Metallic casing enables easier fitting. However, this type demands closer tolerances in the housing bore to ensure the sealing process. Type C Metallic casing with reinforcing cap. Sealing and mounting are identical with type B. This type is applied in case of rougher operating conditions and where larger dimensions are utilized. Less delicate in case of incorrect mounting due to reinforcing cap.
