HIGH PRESSURE SEALS

Description

Pressure-resistant type for use without back-up ring in pressurised units such as hydraulic pumps and motors as well as hydrodynamic couplings. With additional dust lip to protect against exterior soiling. * Used preferably in pressurised units * Reliable sealing of the housing bore, even with increased roughness of the bore, thermal expansion and split housings * Advantages when sealing low viscosity and gaseous media * Additional dust lip as additional seal against moderate to medium dust and dirt ingress from outside * Small axial dimensions (Note: can lead to temperature increase from frictional heat)

Application

Outer casing: elastomer Short, flexible, spring-loaded sealing lip Additional dust lip Sealing lip profile, sealing lip machined on the front face Sealing lip profile, finished sealing lip

Materials

Fluorinated Rubber (FKM) + Nitrile Rubber (NBR)

Description

DA rotary shaft oil seal profiles feature two opposite facing spring loaded elastomer lips with metal case for general bi-directional fluid sealing, fluid separation or contamination exclusion. A stainless steel garter spring provides constant, uniform load of the each elastomer lip on the shaft for the life of the seal. The spring keeps the elastomer lip in contact with the shaft during higher shaft speeds and also helps offset normally occurring compression set and wear of the lip material. * High resistance to gap extrusion. * Particularly strong wear resistance. * Insensitivity to shock loads and pressure peaks.

Application

For use in general pressure applications requiring bi-directional fluid separation or contamination exclusion.
