Oil seals, often referred to as shaft seals or rotary seals, play an essential role in various industrial applications. Among the diverse types of oil seals in the market, the oil seal designated as 20% 35% 7% specifically represents a particular sizing and design that can address unique sealing requirements. In this article, we will explore the significance of oil seals, the specific features of the 20% 35% 7% oil seal, and its applications.

1. Nitrile Rubber Seals (NBR) These are the most common type used due to their excellent oil resistance and durability. They are ideal for general-purpose applications and provide a good balance between cost and performance.

Applications of Wiper Seals

Hydraulic seal kits come in various types, each designed for specific applications and requirements. Common types include O-ring kits, piston seal kits, rod seal kits, and complete sealing kits for hydraulic cylinders. The variation in design and function means that prices can range widely. For example, a simple O-ring kit might cost anywhere from $10 to $50, while a more complex hydraulic cylinder seal kit might range from $100 to several hundred dollars.

- Automotive Systems Found in hydraulic brake systems and power steering units, providing critical sealing functions.

At its core, a cylinder gland seal is designed to ensure that the hydraulic or pneumatic fluid remains contained within the cylinder, preventing leakage that can lead to loss of pressure and efficiency. The seal is typically mounted in a gland, which is part of the cylinder housing. As the piston moves within the cylinder, the gland seal interfaces with its surface, creating a barrier that minimizes fluid escape.

5. Test the Cylinder After reassembly, it’s crucial to test the hydraulic cylinder under a controlled environment to ensure it operates correctly and efficiently, checking for any leaks.

4. Washers and Retaining Rings These small components play vital roles in securing parts in place and ensuring smooth operation.

Oil seals are designed to create a barrier between the moving parts of a machine and the external environment. They are typically made of rubber or elastomeric materials that are resistant to oil, temperature changes, and wear. The primary function of an oil seal is to retain lubricants within the system and prevent the ingress of contaminants such as dirt, water, and debris.

Conclusion

- Rod Seals These are essential for preventing fluid leakage around the piston rod. Rod seals need to accommodate the rod's movement while withstanding wear and tear from friction.

3. Operating Conditions Consider the temperature, pressure, and environmental conditions in which the seals will operate. High-temperature applications may require specially formulated materials to withstand thermal degradation.

One of the key advantages of combi oil seals is their versatile design that allows them to be used in a wide range of applications. They can be used in various industries, including automotive, marine, aerospace, and manufacturing. This versatility makes combi oil seals a popular choice for many engineers and maintenance professionals.

Wiper oil seals, commonly referred to as lip seals or simply oil seals, are mechanical seals used to keep lubricants in and contaminants out of machinery. They are typically made from durable materials such as rubber or elastomers, designed to withstand high pressures and temperatures. The primary function of these seals is to maintain a barrier that prevents the escape of oil, while also preventing dirt, dust, and other contaminants from infiltrating the system.
