Shafting grounding device application While the propeller shaft rotates,the lube oil film is formed at the bearing portions such as intermediate shaft,etc,.with a great difference of potential appearing between proller shaft and hull.This difference of potential constitutes a treat cause to the occurrence of electrolytic corrosion in propeller wing,propeller shaftmpropeller shaft sleeve and so on. shafting grounding device Characters: Propeller shaft grounding Ass'y is the system to minimize the difference of potential between propeller shaft&hull with two netals electrically connected all the time. This equipment can be assembled shaft diameter range 100mm-900mmï¼?special specification according to the specification according to the specification given by the user design
