WAG FKM

Rotary shaft seal with a grooved elastomer outer sheath which fully encases a metal insert as well as a spring-energised sealing lip. In addition, a (WAG FKM) model with a protective lip on the air side is available.

Description
Product group: Rotary shaft seal
Design: A = outer surface rubber-coated
Model: G = protective lip and with grooved outer surface
Seal material: FKM 80
Colour: brown
Stiffening ring: non-alloy steel according to DIN EN 10139
Tension spring: non-alloy spring steel according to DIN EN 10270-1

Areas of application
Sealing of rotating machine elements such as shafts, hubs and axles.

Function
The WAG FKM is a rotary shaft seal for rotating or pivoting shafts with optional protective lip sealing action (WAG FKM) on the side facing away from the medium, against dirt accumulation from the outside. The grooved outer sheath provides improved static sealing for housings with greater thermal expansion because it has a higher press fit allowance. It also prevents permanent skew of the rotary shaft seal. In addition, installation is facilitated because less press-fit force is required.

Media
Mineral oils and greases, synthetic oils and greases, engine, transmission and ATF oils, fuels, aromatic and chlorinated hydrocarbons, broad chemicals and solvents resistance. Please also refer to our media resistance tables.

Operational application limits
Pressure (Mpa/bar): max. 0.05/0.5
Temperature (°C): -30 to +200
Peripheral speed (m/s): ≤ 35
Please also refer to our rotational speed diagram.

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. Please also refer to our general installation instructions.

Remarks
National/international standard dimensions up to 600 mm outer diameter are available on request. However, minimum quantities may be obligatory. Other dimensions and different designs, e.g. double dust protection lip, spiral on the sealing lip, springs or metal inserts made of other steel grades can be produced as well as in all kinds of special designs.
