Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.

What is an Oil Seal?
- 3. Chemical Processing Thick rubber gaskets are resistant to chemicals and can withstand harsh environments, making them ideal for use in chemical processing plants and refineries.
- Power steering systems are crucial components in modern vehicles, allowing drivers to easily steer their cars with minimal effort. One important part of the power steering system is the oil seal, which plays a key role in maintaining the proper function of the system.
- Alignment Checks: This involves verifying the alignment of the seal, shaft, and bore before installation. Use a straight edge or laser tool to ensure concentricity and squareness. Misalignment can cause uneven pressure distribution, leading to early wear and potential leakage.
- In conclusion, oil seals play a critical role in maintaining the performance and longevity of machinery. By preventing the leakage of oil and contaminants, these seals help to ensure that machines operate efficiently and reliably over extended periods of time. With their high-quality materials and precise design, oil seals are a must-have component for any mechanical system that requires reliable sealing solutions.
Failure to install oil seals correctly can lead to failure. Factors such as knocking the seal into place may cause its spring to tilt in the bore or be out of alignment. Consider switching to a solid adhesive and applying it around the surface of the spring to prevent it from loosening.
One way to identify a seal that has not been fitted correctly is to check the rough shear of the rubber. To resolve this issue, align the mounting tool before positioning the seal in place.
(6) Note that there should be a certain amount of lubricating oil on the lip of the oil seal.
Dechengwang provides a full line of seal types, including PTFE seal, which is recognized as the best seal and the future of the seal industry. Amongst all other PTFE component manufacturers, Dechengwang stands out with unique products and services, as well as outstanding manufacturing capabilities.

In this an auxiliary lip is provided along with the regular sealing lip. The additional dust lip protects the main sealing lip against dust and other fine solid contaminants and therefore this type is recommended for use in polluted environments. To achieve a long lifetime a suitable lubricant between the two sealing lips should be applied.
No matter the PTFE machining techniques and other processes used in making mechanical parts, they tend to fail due to some reasons. The same thing applies to oil seals. When they are exposed to some factors, they fail. The factors are stated below alongside the solutions.
