Above, are all the components of an oil seal and all its naming conventions. Beyond selecting the correct size, the three primary selection criteria are Material, Lip, and Case. If you have an oil seal you’d like custom designed and made, send us your specifications through our Oil Seal Design Form.


In conclusion, car engine head gaskets and automotive rubber gaskets are essential components in vehicle systems, contributing to the efficiency, performance, and reliability of automotive systems. Understanding the significance of these gaskets and their proper maintenance and replacement is crucial for optimizing the performance and longevity of the vehicle.
Oil seals come in various shapes to fit the machines and substances to be sealed.
Figure 2 shows the structure and the names of the various components of the most typical oil seal.
The functions of the various components are also indicated in Table 1.

Why use NOK-CN factory-made oil seals?
A wide range of industries rely on oil seals to ensure optimal operation of mechanical assemblies. Components in the industrial and automotive fields, such as pumps, fans, electric motors, and other rotating or moving parts, use oil seals to maintain lubrication and keep contaminants from entering the shaft. Seals are especially useful in applications exposed to extreme environmental temperatures and pressures.

Automotive Rubber Gaskets: Versatile Sealing Solutions
These cassette seals are widely used in wheel-end applications, such as the axles of agricultural machinery or off-road trucks.

These oil seals are created from a low-temperature tolerant compound. Benefits include:
VMQ, also known as silicone, is also used for oil seals, but this is less common because the mechanical strength of VMQ is low and this material has poor wear-resistance This makes it less suitable for dynamic applications, but it can withstand fairly low and high temperatures from -60 °C to 200 °C. Many types of VMQ are also suitable for contact with pharmaceutical and food products, so VMQ is an option worth considering. VMQ oil seals are usually available on request.
