Oil seals can show good sealing performance in combination with properly designed shafts and housings.

Factors in Oil Seal Selection
Radial oil seals are a critical component in the operation of rotating machinery. These seals are designed to prevent the leakage of oil from the housing of the machine while allowing the shaft to rotate freely. They are widely used in a variety of applications, including automotive engines, pumps, turbines, and compressors. 1

4. The sealing function of the oil seal is good and the service life is long. It has the certain adaptability to the vibration of the machine and eccentricity of the main shaft.
No matter the PTFE machining techniques and other processes used in making mechanical parts, they tend to fail due to some reasons. The same thing applies to oil seals. When they are exposed to some factors, they fail. The factors are stated below alongside the solutions.
