Produktdata

Operational application limits

Pressure (Mpa/bar): ≤10 bar depending on the rotational speed See next page:
Temperature (°C): -40 to +100
Peripheral speed (m/s): ≤ 10

Media

Good chemical resistance to many mineral oils and greases.

Function

The ASY is a single-action rotary shaft seal for rotating or pivoting shafts with optional protective lip sealing action (ASY) on the side facing away from the medium, against dirt accumulation from the outside. The shorter, thicker, spring-energized sealing lip enables pressure application of up to 10 bar (depending on the rotational speed). The elastomer outer sheath provides good static sealing, good thermal expansion balance, e.g. in light-metal housing, better sealing with greater roughness and secure sealing for split housings as well as good static sealing with thin fluid or gaseous media.

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.

Applications

Sealing of rotating machine elements such as shafts, hubs and axles when pressurized. The main area of application is in pressurized systems such as pumps and hydro-motors.
