The complete stern tube and sealing system (2): Stern tubes
The slogan ‘The Origin of Sealing Solutions’ suggests that Lagersmit only offers seals. But did you know we also supply the complete stern tube and sealing system including stern tubes and bearings? In a previous blog we gave an introduction to Lagersmit’s bearings, but this blog focuses on complete stern tube systems. Keep reading to find out more about the working principles and how our stern tube system delivers you Peace of Mind.
STERN TUBES: TO REFRESH YOUR MEMORY
The stern tube is installed at the stern of the ship and carries the sliding bearings that are used to support the propeller shaft. The stern tube is filled with a lubrication medium and provides room for needed piping for example oil lines, temperature sensors and the Supreme Ventus® system. Seals are installed at the aft and forward end of the stern tube.
HOW IT WORKS
Every stern tube design is customised according to the customer’s requirements. Because the stern tube can be fully equipped with piping, bearings and seals, the installation can be done within a day. There are various types of stern tube systems available and when making the selection you have to take several factors into consideration.
HOW LAGERSMIT’S STERN TUBE SYSTEM DELIVERS YOU PEACE OF MIND
