- The maintenance of oil seals is another important aspect that affects their longevity. Regular inspection and replacement of worn or damaged seals can prevent costly machinery failures and extend the overall life of the equipment. It is essential to follow the manufacturer's recommendations for maintenance and to use genuine replacement parts to ensure optimal performance.
Common causes of oil seal failure


Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.

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:

In addition to selecting the right type of oil seal, it is essential to consider the operating conditions of the equipment. Factors such as temperature, pressure, and speed can impact the performance and longevity of the seal. Choosing a seal that is rated for the specific operating conditions will help ensure reliable sealing and extended service life.
