Oil Seal N23

Oil Seal N23: Dependable Pressure-Resistant Sealing Solution

The Oil Seal N23 is a pressure-resistant seal designed to provide reliable sealing performance in demanding applications. It features a smooth outer jacket and a sealing lip supported by a short spiral spring. Unlike some other oil seals, the N23 does not have a dust lip.

One of the special characteristics of the Oil Seal N23 is its ability to withstand pressure, thanks to the special design of the sealing lip. This makes it particularly suitable for twist and press applications, as well as pressure-loading units such as pumps or hydraulic motors. The seal ensures a secure static seal within the housing, offering peace of mind and optimal performance even in high-pressure environments.

The Oil Seal N23 is ideal for use with housings that experience high thermal expansion, such as those made of light metals. It is also suitable for shared enclosures and housings with increased surface roughness, providing versatile sealing options. Additionally, it performs exceptionally well when sealing gaseous or thin liquid media. The N23 oil seal offers effective protection against the ingress of external dirt, such as fabrics, ensuring clean and reliable operation.

The application possibilities for the Oil Seal N23 are diverse. It is a reliable choice for twist and press applications, providing dependable sealing performance. Moreover, its pressure resistance makes it an excellent option for pressure-loading units like pumps or hydraulic motors.

The standard material combination for the Oil Seal N23 includes NBR 80 Black as the elastomer, rust and acid-resistant steel (1.4301) for the spring and reinforcement ring. Special materials such as FKM are also available to meet specific requirements. The use of high-quality materials ensures durability and resistance to corrosion, providing long-lasting performance.

When it comes to operating parameters, the Oil Seal N23 operates effectively within a temperature range of -40°C to +100°C. It is compatible with mineral oil-based lubricants and synthetic lubricants. For synthetic lubricants without available experience figures, it is recommended to perform compatibility tests during laboratory or practical test runs. To maintain optimal performance, it is crucial to avoid exceeding an operating temperature of 80°C.

In terms of construction, the Oil Seal N23 adheres to specific guidelines to ensure reliability. The shaft tolerance is ISO H11, guaranteeing a precise fit. The minimum hardness of 45 HRC ensures durability and resistance to wear. The surface roughness of Ra = 0.2 - 0.8 µm and Rz = 1-5 µm contributes to optimal sealing performance. The torsion-free surface condition further enhances the sealing capabilities. The housing tolerance is ISO H8, while the roughness of Ra = 1.6 - 6.3 µm, Rz = 10 - 20 µm, and Rmax ≤ 25 µm ensures a secure and effective seal.

In summary, the Oil Seal N23 is a dependable pressure-resistant sealing solution suitable for various applications. Its special features, versatile application possibilities, compatibility with different materials and operating parameters, and adherence to construction guidelines make it a valuable component in twist and press applications, as well as pressure-loading units. Choose the Oil Seal N23 for reliable sealing performance and peace of mind in demanding environments.
