Table 5: The major special seals, their shapes, and their features
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.

Oil Seals – Everything You Need To Know About
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.

Oil seals are an essential component of many industrial machines and equipment. They play a crucial role in preventing oil leaks, protecting bearings and other crucial parts from contamination, and ensuring the overall smooth operation of the machinery. One popular and widely-used size of oil seal is the 75x100x10 model.

Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.
An oil seal consists of:
A number of variables must be considered when selecting oil seals. There are nine factors that designers and maintenance engineers must evaluate when oil seals are specified:
