WAG

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

Description
Product group: Rotary shaft seal
Design: A = outer surface rubber-coated
Model: G = protective lip and with grooved outer surface
Seal material: NBR 70
Colour: black
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 is a rotary shaft seal for rotating or pivoting shafts with optional protective lip sealing action 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 degree of press fitting. It also prevents permanent skew of the rotary shaft seal. In addition, installation is facilitated because less press-fit force is required.

Media
Generally good chemical resistance to many mineral oils and greases.

Operational application limits
Pressure (Mpa/bar): max. 0.05/0.5
Temperature (°C): -40 to +100
Peripheral speed (m/s): ≤ 12

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.

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 different steel grades can be produced as well as all kinds of special designs.
