What are the main factors that cause the bearing oil seal to leak? What is the impact?

1. The main factors of bearing oil seal leakage
Lack of sealing of bearing oil seal is the main factor causing oil leakage. When the shaft wears and forms a groove, even if the new oil seal is replaced, the contact pressure between the bearing oil seal lip and the shaft is decreased, resulting in too small interference between the oil seal lip diameter and the shaft diameter after installation.
The main reasons for its lax sealing are:
①The quality of the oil seal is poor.
②The shaft or bearing is of poor quality.
③Improper use and maintenance. Bearing measurement error does not mean that the inspection tolerance can be relaxed by 10%
④ improper installation.
⑤ Improper storage and adverse effects caused by environmental pollution.
2. The influence of oil leakage of bearing oil seal
Bearing oil seal is an important part of agricultural machinery and various mechanical equipment. Its performance and quality directly affect the reliability of agricultural machinery and various mechanical equipment.
The life of some bearing oil seals is as long as one year, at least several months or even three to five days, and the oil leaks and is scrapped due to inadequate sealing. This situation has seriously affected the working efficiency of agricultural machinery and various mechanical equipment, not only increased fuel consumption and production costs, but also polluted the environment.
