- In the realm of machinery and equipment, the oil seal serves as a vital component, ensuring smooth operation and extending the life of the machine. This small yet indispensable part plays a crucial role in preventing oil leakage and maintaining the integrity of the lubrication system.
Oil lip seals play a significant role in several industrial applications to avoid intermixing fluids and prevent contaminants and moisture from affecting the bearings. With such a vital role to play, it is essential to choose the right material for these seals. The choice of the material will depend on factors like the type of fluid being sealed, operating temperature, pressure, and compatibility with the operating environment. The following list of materials is typical for making oil lip seals:

Before installing the oil seal, it is important to lubricate it to reduce friction and prevent damage during installation. A silicone-based lubricant is recommended for most applications. If the oil seal is to be installed in a high-temperature or high-pressure environment, a more specialized lubricant may be required.
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.

Choosing the correct type for your application


Sealing Element
A shaft’s surface finishing will determine how effective the sealing will be. The spiral lead and the direction of the finish tool marks have an impact on the sealing effectiveness. Therefore, it’s imperative to ensure that the shaft surface finishing is maintained.
