Stern Tube Seal · Shaft Line Equipment
A water‑lubricated stern tube bearing that uses a composite sleeve to support the propeller shaft without oil, providing EPA VGP compliance and high shock resistance. As a Stern Tube Seal, 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: Shaft diameter 75-1000mm. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
