4. Install the Oil Seal
Improper installation can cause your oil seal to malfunction. While being tapped into place, it can become tilted or misaligned in the bore. That being said, setting it up correctly will help ensure that the sealing process is effective.
Oil seal manufacturing involves the production of precision-engineered seals designed to prevent the leakage of lubricants and the ingress of contaminants in various industrial and automotive applications. The manufacturing process typically includes the selection of high-quality materials, precision molding or machining, and rigorous quality control measures to ensure the reliability and performance of the oil seals. Advanced manufacturing technologies and expertise are essential for producing oil seals that meet the demanding requirements of diverse industries.
Figure 4 shows the features of a JTEKT oil seal.



The purpose of the oil seals is
If the seal is being fitted to original equipment you may have some influence over the shaft and housing bore finish, but if you are replacing a worn seal you still need to take into account the condition of these 2 essential parts.

different types of spark plugs.
ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.
