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.
