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)
