Cause Of The Problem:
The Main Factors Causing Oil Seal Leakage
Loose Oil Seal Is The Main Cause Of Oil Leakage.When The Shaft Is Worn And Grooves Are Formed, Even If The Oil Seal Is Replaced, It Can Not Be Sealed, Because The Contact Pressure Between The Oil Seal Lip And The Shaft Drops, Resulting In Too Small Interference Between The Diameter Of The Oil Seal Lip And The Shaft Diameter After Installation.
1. The Oil Seal Manufacturing Quality Is Poor;
2. Poor Shaft Or Bearing Quality;
3. Improper Use And Maintenance;
4. Improper Installation;
5. Improper Storage, Caused By Environmental Pollution
