System for Propeller Shaft Earthing

A turning propeller-shaft on a ship becomes electrically insulated from the hull by the lubricating oil film in the metal bearings or through the use of non-metallic bearings materials. It is absolutely necessary to ground the ship's propeller shaft to the hull. The heavy electrical current flowing through the bearings and gearbox to the hull will be minimized by our Propeller Shaft Earthing System.

The Propeller Shaft Earthing System will prevent early maintenance costs of the ships propeller and shaft bearings. The system has a long lifetime because of the high compositions of silver in the brushes.
