The Oil Seal O18 is a high-quality oil seal designed for single-action sealing applications. It features a coil spring-supported sealing lip and a smooth elastomer sheathed outer diameter. This oil seal is specifically designed for outside sealing, making it an effective solution for various applications.
One of the key application possibilities for the Oil Seal O18 is in the separation of two media in rotating machine elements. It ensures a reliable seal, preventing the mixture or contamination of different fluids or substances. This makes it an ideal choice for applications where the separation of media is crucial.
The standard material combination for the Oil Seal O18 includes NBR 70 Black as the elastomer, spring steel according to DIN EN 10270-1 for the spring, and sheet steel according to DIN EN 10139 for the reinforcing ring. Special materials such as FKM, Silicone, ACM, HNBR, CR, and EPDM are also available to meet specific requirements. This ensures compatibility with different operating conditions and extends the versatility of the seal.
Operating parameters for the Oil Seal O18 include a temperature range of -40°C to +100°C, making it suitable for a wide range of environments. The seal is designed for unpressurized applications, with a maximum pressure rating of 0.05 MPa. It can withstand a maximum circumferential speed of 10 m/s, allowing for efficient sealing performance in high-speed applications. The Oil Seal O18 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. It is important to note that the operating temperature should not exceed 80°C to ensure optimal performance and longevity.
Construction notes for the Oil Seal O18 provide guidance for optimal installation and performance. The shaft tolerance is ISO H11, ensuring a precise fit and proper sealing. The minimum hardness of 45 HRC guarantees durability and resistance to wear. The surface roughness ranges from Ra = 0.2 - 0.8 µm, Rz = 1-5 µm, and Rmax = 6.3 µm, contributing to optimal sealing performance. The torsion-free surface condition further enhances the seal's effectiveness. The housing tolerance is ISO H8, while the roughness ranges from Ra = 1.6 - 6.3 µm, Rz = 10-20 µm, and Rmax ≤ 25 µm, ensuring a secure and reliable seal.
In summary, the Oil Seal O18 is a reliable single-action sealing solution suitable for a variety of applications. Its coil spring-supported sealing lip, smooth elastomer sheathed outer diameter, and compatibility with different materials and operating parameters make it a versatile choice for outside sealing applications. Choose the Oil Seal O18 for reliable sealing performance, efficient separation of media, and extended durability in rotating machine elements.
