Stern Tube
A stern tube is a hollow tube-like structure that runs through the stern of a ship and supports the propeller shaft. It is an essential component of the ship's propulsion system, as it allows the propeller shaft to rotate freely while maintaining a watertight seal between the stern tube and the hull. The stern tube is typically made of steel and is lined with a bearing material, such as brass or bronze, to reduce friction and wear. It is also equipped with a stuffing box, which is a device that compresses packing material around the propeller shaft to prevent water from entering the ship. Regular maintenance and inspection of the stern tube is crucial to ensure the safe and efficient operation of the ship's propulsion system.
