 | PROPFLEX N Coupling
PROPFLEX N Coupling is designed to be installed on board of all boats with high vibrations isolation requirements. It has to be placed between the gearbox and the propeller shaft. It's compact and radially dismountable. The N type is suitable for all applications where there is no thrust load. Higher deflections are permissible.
| Torque: |
|
|
|
|
| 2.40 kNm to 41.00 kNm | | Applications: |
| - Rigidly and A/V-mounted gearboxes
