Some aspects to consider when selecting this component are:
Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
- In conclusion, oil seals play a crucial role in preventing oil leakage in mechanical systems. By understanding the different types of oil seals available and their unique characteristics, engineers and maintenance professionals can select the most suitable seal for their specific application. Proper selection, installation, and maintenance of oil seals are essential for ensuring the efficient and reliable operation of machinery and equipment.

- As technology advanced, so did gasket automation. Precision became a key focus, with computer-controlled cutting devices replacing handcrafted methods. These CNC (Computer Numerical Control) machines could replicate exact measurements and patterns with minimal waste, optimizing material usage and lowering costs.

- The process of creating custom molded gaskets begins with understanding the specific needs of the application. Engineers work closely with clients to determine the ideal material, thickness, and compression set for the gasket. This information is then used to create a detailed mold, which is used to shape the gasket material under high pressure and temperature.

Choose a seal that has the appropriate dimension needed for your application. The seal should properly fit the space between the stationary and rotating parts.
20mm rubber gasket. Many rubber compounds are immune to water, making these gaskets suitable for outdoor applications or anywhere moisture may be present. They also exhibit resistance to many chemicals, expanding their utility in laboratories, manufacturing facilities, and other settings where corrosive substances are handled. (1) Shaft speed Due to design and structural reasons, high-speed shafts should use high-speed oil seals, low-speed shafts should use low-speed oil seals, and low-speed oil seals cannot be used on high-speed shafts, and vice versa.

Requirements of the shaft
Even more important than a correct interference fit of the Oil Seal is a perfectly smooth shaft in the region of the seal, particularly if shaft surface speed is high and the medium to be sealed is under a certain amount of excess pressure. The surface roughness of the shaft depends on the average profile depth Ra of the tool marks caused by the machining process. Oil Seals made of PTFE require, independent of the surface speed, a surface roughness of between 0,1 to 0,2 mm, because PTFE has less wear resistance than rubber seals. For normal circumstances, the shaft in the region of the seal must have a surface roughness of approximately: To summarize, the surface of the shaft in the region of the seal should not have noticeable machining marks. For pivoting shafts and other difficult or critical sealing applications, it is recommended that Oil Seals with a helical groove hydrodynamic pattern, which has a pumping effect, be used. When grinding and polishing, an axial movement of the grindstone along the shaft must be avoided in order to prevent machine lay.
1. Pressure: Many oil seals are used in high-pressure applications, so understanding the working pressure of your components is very important.
