This product is equipped with a tension spring and a protective lip, enclosed in a closed metallic outer casing reinforced with a stiffening plate. The sealing material is NBR, and the stiffening plate is made from unalloyed steel (DIN EN 10139, DIN 1624). The spring is crafted from spring steel (DIN EN 10270-1).
Engineered for dynamic sealing of rotating shafts regardless of rotation direction, this product ensures an effective static seal between the sealing lip and the shaft when stationary. The protective lip prevents external dirt accumulation, while the metallic outer jacket guarantees a tight and precise fit. The stiffening plate enhances rigidity. It provides limited sealing for low-viscosity and gaseous media, as well as in split housings. However, increased friction can lead to a rise in temperature.
This product is ideal for challenging installation conditions or larger diameters, offering protection against moderate to medium dust and dirt accumulation from outside. It ensures a tight and precise fit, with a long service life. Its reliable design is suitable for a wide range of moderately demanding industrial applications, providing an excellent price/performance ratio. Manufactured by certified external suppliers, it guarantees high quality and reliability.
This product is well-suited for heavy mechanical engineering, construction and agricultural machinery, rolling mills, and wind power plants.
