Areas of application

Sealing of rotating machine elements such as shafts, hubs and axles. Particularly for the separation of two media or extreme dirt accumulation from the outside.
Function
The RS WAD/RS WBD rotary shaft seal is used for the separation of two media or extreme dirt accumulation from the outside for rotating or pivoting shafts.

The RS WAD is a double action rotary shaft ring for rotating or pivoting shafts. The elastomer outer sheath provides good static sealing, good thermal expansion balance e.g. in light-metal housings, better sealing with greater roughness and secure sealing for split housings as well as good static sealing with thin fluid or gaseous media.

Tight and accurate fitting is achieved by the metal outer casing. The RS WBD model has limited sealing action with thin fluid or gaseous media and in split housings.
To guarantee high static sealing on the outer surface, better surface treatment of the housing bore is necessary or an additional coat of paint should be applied to the outer casing.

Media

Good chemical resistance to many mineral oils and greases. Please also refer to our media resistance tables on page 17 of this catalogue.
Operational application limits
Pressure (Mpa/bar): ≤ 0.03/0.3
Temperature (°C): -40 to +100
Peripheral speed (m/s): ≤ 6
Please also refer to our rotational speed diagram on page 15 of this catalogue.

Installation

Suitable tools should be used for installation. It is recommended that the installation housing is designed to provide the rotary shaft seal with axial support. The space between the sealing lips must be 2/3 filled with grease. Please also refer to our general installation instructions on page 25 of this catalogue.

Remarks

The nominal widths mentioned on the following pages represent the standard dimensions.

Other dimensions and different designs, e.g. springs or metal inserts made of other steel grades can be produced as well some special designs. Minimum quantities may be obligatory for dimensions outside of the standard.

The RS WAD/RS WBD models can also be produced in fluoro rubber (FKM).
