Installation Specification
| Rotation Without Fluid | Min Flow Rate to Operate Seal (In Case Fluid is Coolant) | * Thrust loading to spindle side |
|---|---|---|
| ✔ | Over 10 L/min | 873N |
| ✔ | Over 2.64 gal/min | 873N |
Note)
* Thrust loading to spindle side
- Thrust loading is directly proportional to fluid pressure.
- In case fluid pressure is 7 MPa (1,015 psi, 70 bar).
