- Metal, such as steel, which provides strength and durability.
- When the oil seal fails, it can lead to a variety of issues. Leaking oil can cause the wheel bearing to overheat, reducing its lifespan and potentially causing failure. Contaminants entering the bearing can lead to increased friction and wear, necessitating costly repairs. Moreover, oil leakage on the brakes can compromise their effectiveness, posing a significant safety hazard.
- Spark plugs play a pivotal role in the internal combustion engines of vehicles, acting as the ignition source that triggers the combustion process. This concise guide aims to delve into the world of spark plugs, their function, types, and importance, drawing insights from various PDF resources available.
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:
Fluid Types - Various oil seals are able to withstand interactions with oils, fuels, grease, water and more. Knowing what type of fluid the rotary shaft seal will be in constant contact with will ensure the longevity of the seal and surrounding components.


Installation of the oil seal
AS
All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.
Fluorine rubber (FKM, Viton™)
Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.
