1. Prevents Leakage
-
Keeps lubricants (oil or grease) inside machinery.
-
Reduces the risk of contamination and maintains proper lubrication.
2. Protects Against Contamination
-
Blocks dirt, dust, water, and other contaminants from entering the system.
-
Extends the service life of bearings, shafts, and other moving parts.
3. Reduces Wear & Tear
-
Maintains a thin oil film between the sealing lip and shaft.
-
Minimizes friction, preventing premature damage to shafts and bearings.
4. Seals Under Pressure
-
Special designs can handle high pressure environments.
-
Prevents blowout of lubricants in hydraulic or pneumatic systems.
5. Enhances Efficiency
-
Reduces power loss caused by friction.
-
Improves energy efficiency in rotating equipment.
