Propeller Shaft · Shaft Line & Propulsion
A forged steel propeller shaft with a nominal diameter of 400 mm supplied by Wärtsilä, designed for main propulsion lines on merchant vessels. As a Propeller Shaft, it is normally installed in the propulsion train between the prime mover, gearbox and propeller or within the stern-tube and propulsor arrangement. In that role, its primary purpose is to transmit torque, support the shaft, seal the hull penetration or control propeller thrust according to the listed component. Shafts, bearings, seals, couplings, CPP mechanisms and shaft generators perform different roles, so alignment, lubrication and wear limits remain component-specific. Capacity: 12000 kW. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
