How does an Oil Seal Work
Minor lip The minor lip prevents the entry of dust and contaminants from outside.
Lubricant can be retained in the space between the main lip and the minor lip.
diesel spark plugs. This ensures that the fuel-air mixture is ignited properly and that the combustion process is as efficient as possible. This is important for diesel engines, which rely on precise combustion to generate power.
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.

The basic principle of an oil seal is fairly straightforward. It is installed adjacent to the bearing, with the flexible lip against the rotating shaft and the casing pressed into the housing to hold the seal in place. It’s important that the sealing lip is lubricated to prevent it from overheating as a result of any generated friction. It’s also crucial to understand which type of seal is appropriate for your particular machinery. Before selecting your seal, consider the environment, temperature, pressure and shaft speed of your machine, as well as the type of medium the seal will come into contact with during operation. These considerations will all determine the size, colour, and type of lip material or sealing element to choose, and whether it can be sealed in or sealed out.
What materials are available?
NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.
Lubricant can be retained in the space between the main lip and the minor lip.
Oil seals are used in a great many devices for steel production equipment.
Figure 7 shows the places where each seal type is used in a rolling mill.
Oil seals are typically classified based on their sealing capabilities, with common types including lip seals, mechanical seals, and hydraulic seals. Lip seals are the most basic type, consisting of a flexible lip that seals against the shaft. Mechanical seals use sliding or rotating components to create a seal, while hydraulic seals are designed for high-pressure applications.
