This product features a tension spring but lacks a protective lip, enclosed within a metallic outer casing with a stiffening plate. The sealing materials used are NBR and FKM, while the stiffening plate is crafted from unalloyed steel (DIN EN 10139, DIN 1624). The spring material is made from spring steel (DIN EN 10270-1).
Designed for dynamic sealing of rotating shafts, independent of the direction of rotation, this product ensures a good static seal between the sealing lip and the shaft when stationary. The metallic outer jacket guarantees a tight and precise fit, while the stiffening plate provides increased rigidity. It also offers limited sealing for low-viscosity and gaseous media, as well as in split housings.
This product is well-suited for challenging installation conditions or larger diameters, ensuring a tight and precise fit. It offers a long service life and features a reliable design that caters to a broad spectrum of moderately demanding industrial applications, delivering excellent value for money. Manufactured by certified external suppliers, it guarantees high quality and reliability.
Ideal for heavy mechanical engineering, this product is also suitable for construction and agricultural machinery, rolling mills, and wind power plants.

| Material | Description | Temperature Range |
| NBR | NBR (Nitrile Butadiene Rubber) is a highly valued sealing material due to its excellent resistance to oils, fuels, and other chemicals, making it an ideal choice for applications in the automotive and aerospace industries. With a temperature operating range, NBR provides versatility under varied environmental conditions. Very cost effective option. | -40°C to 120°C -40°F to 248°F |
| FKM | FKM (Fluoroelastomer) is highly regarded in the sealing industry for its exceptional resistance to high temperatures, chemicals, and aging, making it indispensable in aerospace, automotive, and chemical processing sectors. This material thrives across a wide temperature range, enabling its use in extreme conditions where other materials would fail. FKM’s remarkable compatibility with a wide variety of chemicals, including oil, fuel, and solvents, along with its ability to withstand harsh environmental factors, ensures its preference for high-performance seals, O-rings, and gaskets. Its robustness and longevity under aggressive conditions underscore FKM’s value as a premier choice for demanding sealing applications. | -20°C to 200°C -4°F to 392°F |
