The group of oil seals used in dynamic applications include radial shaft seals that seal a rotating shaft around its circumference. They are also known as lip seals, but in this blog we will use the term oil seals.
Lip type When the oil seal material and the chemical are not compatible, there will be a chemical attack, which increases at high temperatures. The only way to remedy this is to select the right material for your application. If you’ll be dealing with harsh chemicals, choose oil seals that are made with reliable materials for their compatibility.
- Other maintenance factors, such as insufficient lubrication inside the engine.

What material are oil seals made from?
Fluid side face The front-end face of the seal is called the nose. The nose is made of rubber and forms a gasket seal when compressed on the housing shoulder.
If you have prepared the assembly properly, then you are already largely on your way to a successful installation. The assembly of the oil seal itself is not complex. It is, of course, important that it is done properly in view of the longevity and reliability of the seal.

Have you found the right oil seal for your application? The next step is a precise and error-free assembly, so that the oil seal is fitted without being damaged. If you are replacing an existing oil seal, you must first disassemble it with the same care and precision. In this article, you will read all about the different steps of an appropriate (dis)assembly process that contributes to optimal operation within the application.
To act as a physical barrier retaining the lubricating oil where it is bound to be.
NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.
The sizes of industrial oil seals typically range from 0–33cm. These varieties are designed for temperature fluctuations. If your seal matches the intended equipment, the machine will perform optimally.
