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

Advantage:
1. The Oil Seal Structure Is Simple And Easy To Manufacture. Simple Oil Seals Can Be Molded At One Time, Even The Most CompliC.A.Ted Oil Seals Are Manufactured Using Oil Seals
Not CompliC.A.Ted. The Metal Frame Oil Seal Also Only Needs To Go Through The Processes Of Stamping, Gluing, Inlaying, And Molding To Form The Required Oil Seal With Metal And Rubber.
2. The Oil Seal Is Light In Weight And Less Consumable. Each Oil Seal Is a Combination Of Thin-Walled Metal Parts And Rubber Parts, And Its Material Consumption Is Very Small, So The Weight Of Each Oil Seal Is Very Light.
3. The Installation Position Of The Oil Seal Is Small, The Axial Size Is Small, It Is Easy To Process, And The Machine Is Compact.
4. The Oil Seal Has Good Sealing Performance And Long Service Life. It Has Certain Adaptability To The Vibration Of The Machine And The Eccentricity Of The Spindle.
5. The Oil Seal Is Easy To Disassemble And Inspection Is Convenient.
6. The Oil Seal Is Cheap.
