Sealing principle: Since there is an oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has fluid lubrication characteristics.
The interaction of the integrated seals with the shaft follows the dynamics of the PTFE seals. Often an additional dust seal (rubber lip or felt strip) provides an effective barrier against contaminating particles.
5. TYPES OF FLUID: Numerous oil seals can interact with oils, fuels, grease, water and more. However, know exactly what type of fluid the rotary shaft seal will be in contact with will ensure the longevity of the seal and the machinery.
- In the realm of automotive engineering, the oil seal serves as a vital component, ensuring the smooth operation and longevity of an engine. This,,。,,。
- Oil Seal The Crucial Component in Machinery Performance
When installed, the oil seal’s flexible lip is placed against the rotating shaft, and the casing is pushed into the housing for support. It is crucial that the sealing lip is lubricated to avoid overheating caused by friction.
Refit all the components in the reverse order of dismantling.
Once you have selected the most suitable seal available, considering the environment, temperature, shaft speed, pressure, lubrication availability, as well as the size, of course, the seal should be stored adequately and then fitted properly. Here are a few suggestions that could help:-
Different types of rotary shaft seals are available in the market, including radial lip, axial lip, and mechanical face seals.
