What are double lip oil seals

Double lip oil seal is a rotating shaft seal with two sealing lips. The main purpose of double lip seals is to remove pollutants while retaining lubricants.

Functions of the seal lips

The two lips of a double lip oil seal have different functions. The main lip is responsible for retaining lubricants and preventing leaks, while the secondary lip provides additional protection to prevent contaminants such as dirt, dust, and water from entering.

In addition to its main function of preventing leakage and pollution, double lip seals can also help reduce friction and wear on the shaft. By maintaining a thin film of lubricant between the sealing lip and shaft, a double lip seal helps to reduce friction and heat generation, thereby extending the service life of the seal and shaft.
