The lip is specially designed to ensure the oil seal works effectively with the different forces that arise during rotation. Many different designs and materials are used, so countless types of oil seals are available. These are chosen according to the application; pumps, gearboxes, wheels, and many other rotating applications where fluids need to be sealed. They are used in a variety of sectors, such as the chemical industry, manufacturing, wind turbines, automotive sector, food industry, and more. Oil seals are used in nearly all sectors.

Car iridium spark plugs are a popular choice for modern vehicles due to their durability, high melting point, and superior conductivity. Iridium spark plugs offer enhanced performance and longevity compared to traditional copper or platinum plugs. The use of iridium in the electrode design allows for a smaller center electrode, promoting more efficient combustion and improved engine performance. Car iridium spark plugs are known for their ability to maintain optimal engine performance over an extended service life.

1. Oil seals have three basic components: sealing element, metal case, and spring.

Most ERIKS oil seals, such as the types M, MST, R and RST, are made of NBR as standard.

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.

For the housing stop installation technique, set the seal depth flush with the bore’s interior shoulder. This technique ensures that the seal is perfectly aligned with internal housing components. A depth gauge can be crucial here to confirm that the seal is positioned correctly.
