Highly Flexible Coupling
There are specialized highly flexible coupling for marine gearbox 300 series that can be selected by customers.
Shaft Coupling
Except supply standard 300 Advance marine gearbox, we can also provide customers with shaft coupling according to the shipyard drawing.
Marine Gearbox with PTO
For the convenience of mounting small-sized accessories such as water pumps, generators, etc, in the engine cabin model 300 can be equipped with auxiliary power take-off shaft (PTO, capacity is 0.044kW/rpm), which is an extended transmission shaft from the rear plate of the housing.
Note: Advance 300 Gearbox with PTO is supplied only on request.
