Seawater Propeller Shaft Bearings

  1. 1. Eliminates Oil Discharge from Commercial Ships SEAWATER LUBRICATED PROPELLER SHAFT BEARING
  2. 2. SEAWATER LUBRICATED PROPELLER SHAFT BEARING A seawater lubricated open system uses seawater as the lubrication medium in place of oil. The seawater is taken from the sea, pumped through non-metallic shaft bearings and returns to the sea. No stern tube oil is needed. There is no aft seal; only a forward seal to prevent seawater from entering into the engine room. Proven materials and new designs of non- metallic bearings now offer performance similar to metal shaft bearings.
