What are Oil Seals and how do they work?
Figure 5 explains the JTEKT seal numbering system.
Seal numbers consist of
(1) the seal type code,
(2) the spring code,
(3) the lip type code,
(4) the dimensional numbers, and
(5) the special type code,
and Table 6 shows examples of each of these codes/numbers.
An oil seal, also known as crankshaft retainer, is a small device, but essential to ensure the proper engine operation. It plays a key role in all moving parts of an engine, acting as a physical barrier. This mechanical seal fulfils the dual purpose of sealing a rotary shaft to maintain the necessary lubrication (avoiding leaks) and preventing other foreign matter from contaminating shafts and bearings in the rotary shaft equipment.
Do you still have specific questions about oil seals installation or want to know the right type for your application? Then please contact our specialists. They will be happy to help you with information and advice.
Among the most common causes of oil seal failure are:

distributor oil seal. It is important to make sure that the new seal is properly seated and sealed to prevent any oil leaks in the future.
Depending on the application, premium lip materials may need to be used, such as Ethylene-acrylic (Varmac®). This material features good abrasion and dry running capabilities, higher heat capabilities than nitrile and polyacrylate, and better low-temperature performance than polyacrylate.

In conclusion, installing oil seals correctly is an important step in maintaining the performance and efficiency of rotating machinery. By following these steps, you can ensure that your oil seals are installed correctly and will provide a leak-free performance. If you have any questions or concerns about installing oil seals, consult with a professional or refer to the manufacturer's instructions. Proper installation of oil seals can help to extend the life of your machinery, reduce the risk of leaks, and ensure a safe and efficient operation.
