WAX

The WAX rotary shaft seal is a special type with the sealing lip on the outside (exterior sealing). It consists of a metal insert with an elastomer inner sheath as well as a spring-energised sealing lip facing outwards.

Description
Product group: Rotary shaft seal
Design: A = inner surface rubber-coated
Model: X = sealing lip on outside
Seal material: NBR 70
Colour: black
Stiffening ring: non-alloy steel according to DIN EN 10139
Druckfeder: non-alloy spring steel according to DIN EN 10270-1

Areas of application
Sealing of rotating machine parts, either against stationary or rotating housings, such as axle sealing in agricultural and construction machinery.

Function
The WAX is a single action rotary shaft seal for stationary or rotating housings. The elastomer inner sheath (shaft side) provides good static sealing, good thermal expansion balance, optimal sealing with greater roughness and thin fluid or gaseous media. As a result of the centrifugal force at higher revolutions, the sealing lip of the WAX design is pressed outwards which intensifies the friction and sealing action.

Media
Good chemical resistance to many mineral oils and greases. Please also refer to our media resistance tables.

Operational application limits
Pressure (Mpa/bar): ≤ 0.05/0.5
Temperature (°C): -40 to +100
Peripheral speed (m/s): ≤ 10
Please also refer to our rotational speed diagram.

Installation housing
The installation housing of a WAX should be executed as for a standard shaft seal in accordance with DIN 3760. Consideration must be given to the fact that the static grip of the rotary shaft seal is on the shaft and the contact surface in the housing. The surface qualities must be observed accordingly.

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 standards up to 600 mm inner diameter are available on request. However, minimum quantities may be obligatory. Other dimensions and different designs, e.g. dust protection lip or the energised spring and/or metal insert made of other steel grades can be produced as well as some special designs.
