Regular inspection and maintenance of wheel hub oil seals and steering oil seals are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of these seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the vehicle's wheel hubs and steering mechanisms.

There are several materials used to manufacture oil seals. They are discussed below.

MAKING THE CHOICE OF AN OIL SEAL VS. MECHANICAL SEAL
Nitrile (NBR) Oil Seals
Silicone oil seals, which are also called VMQ, have strong resistance to temperature, which ranges from -140 degrees Fahrenheit to 392 degrees Fahrenheit. They are also resistant to ozone, light, and harsh weather conditions. Silicone is frequently used in hydraulics and pneumatics, as well as in the food and medical industries. Due to the material’s transparency and flexibility, it’s commonly chosen for the manufacturing of o-rings, molded parts, and flat seals, as well as electrical insulators.

In addition to carbon buildup and oil leakage, black spark plugs can also be caused by overheating. If the engine is running too hot, it can cause the electrodes on the spark plugs to wear down and become coated in carbon deposits. This can lead to poor engine performance and reduced fuel efficiency. It is important to monitor the engine temperature and address any overheating issues promptly to prevent damage to the spark plugs.
Oil seals come in various shapes to fit the machines and substances to be sealed.
Figure 2 shows the structure and the names of the various components of the most typical oil seal.
The functions of the various components are also indicated in Table 1.

Today, traditional oil seals have to compete with a new variant oil seal, which is used in most modern engines.
