Kaco Contrary to lip seals, which are used for sealing purposes in the case of liquid and gaseous media, scrapers have no pronounced sealing function but are used to prevent the penetration of foreign matter into the system. The soil and dust deposited on the extended piston rod must be completely removed by the scraper lip. For this purpose, the lip is designed in such a way that, when installed, its front surface forms a right angle to the piston rod. As a result of this, abrasive particles are prevented from sticking onto or becoming embedded in the contact surface of the lip.

For normal applications, scrapers of NBR materials are manufactured with a Shore hardness of 80 — 90 and they also guarantee a long service life in the case of extreme stresses. Suitable FKM materials are available for special applications such as, for example, high operating temperatures.

QAN scrapers require only a small installation space. It is merely necessary to have a hole into the housing or housing cover in the height of the metallic support piece. When installed, the lip of the scraper projects over the machine components and this prevents the scraped soil from accumulating in the area of the lip and leading to malfunctions. If the installation instructions (page17) are observed, no-problem, and easy installation of these scrapers, which are pressed in previously with the metal component (figure 32), is possible. A good seat in the machine component is guaranteed by the provided press-fit. Corrosion is prevented by the rubber layer on the lip-side of the support element.
