The self-retaining EW seal/wiper combines the properties of the proven E9 high-temperature seal with a metallic wiper for particularly dirt-prone and harsh environments. Thus, the EW seal/wiper provides a scraper function in addition to the sealing function. It is used for scraping strongly adhering particles off the cylinder rod, thereby protecting the seal against excessive wear. The combination of the metallic wiper and wear-resistant sealing compound achieves considerably longer service life.

• Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
• Bi-functional element: seal and wiper.
• Good wear resistance.
• Robust seal profile for harshest operating conditions.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Identical housing for E7, E8, E9, EU, EF, EN, EW, ET.
• Easy snap assembly with assembly aids.

Range of application:
The seal/wiper EW is suitable for use in environments that are particularly prone to dirt and in high temperatures, such as crust breaker cylinders, which are used in aluminum production.
