Oil Seal Installation





Garter springs are generally used when the lubricant is oil, as it provides the necessary downward force to maintain a tight seal. However, when grease is the lubricant, garter springs can often be eliminated. Due to its low viscosity, grease doesn’t require as much downward force to maintain an effective seal.

B) Housing-bore eccentricity
As shown in Figure 9, housing-bore eccentricity is defined as being twice the eccentricity between the housing-bore center and shaft rotation center.
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:
Antioxidants: Antioxidant additives work to slow oxidation and the forming of deposits in motor oil. They also help keep the engine clean and extend the life of the motor oil.
Some disadvantages of NBR are poor ozone, sunlight and weather resistance as well as limited high temperature and flame resistance. For higher temperature resistance, a much better material to use is Silicone.
Replacing gaskets and oil seals
• Fluorine rubber
A shaft oil seal, also known as a lip seal, is typically made of rubber or other flexible materials, with a lip that seals against the rotating shaft. It is designed to effectively seal the interface between the shaft and the housing, preventing the entry of dirt, dust, water, and other contaminants that could potentially damage the machinery.
