Description
  1. Corrosion Protection: The bearing housing anode serves as a sacrificial metal component, typically made from zinc, aluminum, or magnesium alloys. It is designed to corrode preferentially over the metal surfaces of the bearing housing, protecting it from corrosion and extending its lifespan.
  2. Material Composition: Bearing housing anodes are commonly made from highly active metals such as zinc due to their excellent sacrificial properties. These metals have a more negative electrochemical potential than the materials they protect, ensuring they corrode first and provide protection to the bearing housing.
  3. Installation: The bearing housing anode is securely attached to the exterior surface of the bearing housing using mounting bolts or screws. It is strategically positioned to provide comprehensive protection to the bearing components from corrosion.
  4. Electrolytic Action: When submerged in water, the bearing housing anode undergoes galvanic corrosion, releasing electrons to the surrounding metal surfaces of the bearing housing. This sacrificial action forms a protective layer on the bearing housing, preventing corrosion and extending its service life.
  5. Inspection and Replacement: Regular inspection of the bearing housing anode is essential to monitor its condition and effectiveness. Anodes should be replaced when they have significantly corroded or depleted, typically when approximately 50% of their original mass is consumed.
  6. Compatibility: Bearing housing anodes are designed to be compatible with specific bearing housing configurations and marine propulsion systems, ensuring proper fitment and effectiveness. It’s essential to select anodes that are specifically engineered for the make and model of the bearing housing.
