The Duramax marine bearings are engineered with a proprietary formulation of extremely tough chemical and oil resistant nitrile rubber polymer lining, molded and firmly bonded into a naval brass or non-metallic shell. Groovers run the entire length of the rubber marine bearing allowing for maximum lubricating water flow and dissipation of frictional heat. The rotational power of a ship’s propeller is determined by the power produced by the marine engine to rotate crankshaft. The crankshaft of the main engine is supported and connected to the connecting rod via main bearings whose main function is to transmit the load without any metal to metal contact. This is achieved by choosing special materials for manufacturing main bearings which floats the journal pin of the rotating crankshaft when lube oil is supplied to it. Properties of Duramax Marine Bearings:   It must be anti friction resistant It must be of anti-corrosive type Good running in and grinding in abili...

For years, mariners have depended on sacrificial seashield marine zinc anodes as a means to counter corrosion. Zinc anodes have ranked as the most popular ones in this category. If you want to protect your boats hull and body work from corrosion then you best learn all you can about seashield marine zinc anodes. These simple little anodes can save you a ton of money in the long run. Typically, a seashield marine zinc anode will corrode as it protects another metal that is lower than itself in the galvanic series of metals and alloys.   Seashield Marine Zinc Anodes: Best for Corrosion Prevention How Do Sacrificial Seashield Marine Zinc Anodes Work? If two dissimilar metals come into contact underwater a constantly occurring stream of electricity passes from one metal to another through water. Subsequently, the metal that is more active among the two will corrode first. Thus, when you install a sacrificial seashield marine zinc anode to the hull or propeller, the an...
