Scana Propeller Shaft 300
A 300 mm diameter forged‑steel propeller shaft from Scana, intended for the main propulsion line of merchant vessels and designed to transmit torque between gearbox and propeller with high fatigue resistance; source-listed capacity 300 mm diameter. The supplied category identifies it as Propeller Shaft, and it is normally installed in the main propulsion shaft line between the engine or gearbox and the propeller. In that role, its primary purpose is to transmit propulsion torque while remaining accurately aligned and supported by shaft bearings. Propeller shafts extend to the propeller and stern tube, while intermediate shafts connect shaft-line sections inside the vessel; both are critical rotating structural components. Within the supplied list, this entry is distinguished from neighbouring variants by its model designation and the explicitly listed capacity; no further model-specific difference is stated in the source. No additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Service & Maintenance
Inspect shaft surfaces where accessible, flange joints, coupling bolts, alignment references and bearing behaviour. Review vibration, bearing-temperature and alignment trends and pay particular attention after grounding, propeller damage or major propulsion work. Non-destructive examination should follow the approved survey or repair plan. Refer to the manufacturer and class documentation for the exact figure for alignment, runout, crack and wear limits.
