The main cause of oil seal leakage

The main causes of bearing seal leakage are:
1, due to the dimensional tolerance does not meet the standard specifications, so that the outer edge of the oil seal with the cavity of the static sealing surface deformation;
2. Cracking of the material due to the harsh working conditions, especially the cracks on the sealing edge of the oil seal;
3, due to the working conditions are too harsh and incompatible rubber elastomer and the working medium caused by increased hardness of the rubber, or the hardness of the elastomer is too high;
4. The sealing medium swells the rubber and reduces the hardness of the rubber, thereby causing premature aging and wear of the oil seal;
5. Corrosion from the shaft to the sealing lip area will leave a permanent fault potential for the sealing system's sealing performance;
6, lubricant failure and the system is in a dry state, so that the seal lip wear quickly;
7, comprehensive aging, both rubber and elastomer sealant aging;
8, in the sealing lip at the formation of "oil carbon" dirt, so that the seal lip seal was lifted, causing leakage of the sealing system failure;
9. The seal lip of the oil seal no longer follows the vibration of the shaft surface and the bouncing of the shaft;
10. Premature wear of contaminants from the inside of the seal into the sealing edge causes premature wear of the shaft surface and the sealing lip;
11, the assembly process is not standardized caused by the contact surface of the shaft surface is damaged and cause premature wear of the sealing lip;
12. Sealing edges are damaged during storage, transportation and assembly.
