Key parameters

| Material | Metal shell + NBR |
| Function | The key to achieving an effective dynamic seal lies in the rubber sealing lip within the structure. Once installed, this lip presses firmly against the surface of a high-speed rotating shaft, creating an extremely thin oil film. This film serves a dual purpose: it provides a sealing effect while ensuring that the oil is not completely wiped away, thereby maintaining a balance between lubrication and sealing during long-term operation. |
