Oil seals are used to fill gaps between stationary and revolving parts of equipment, often known as radial shaft seals or rotary seals. These seals are frequently employed to keep impurities out and prevent lubricating oils, hydraulic fluids, or other liquids from escaping out of the system. An oil seal features:

Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.

It is possible to get custom-made seals manufactured at reasonable rates from good-quality manufacturers if the readymade seal specification doesn’t meet the requirement.

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.
