Duramax DuraBlue Greaseless Rudder Bushing


DuraBlue is a self lubricated composite bushing designed for use in highly loaded oscillatory applications such as found in rudder, pintle and stearing gear assemblies. DuraBlue needs no lubrication and is exceptionally wear resistant with an extremely long wear life. It has a low coefficient of friction value of 0.04 to 0.08, resulting in no stick-slip during operation. DuraBlue experiences virtually no swelling in seawater, and a very low thermal coefficient of expansion. Its proprietary fiber matrix greatly extends wear life and a self-lubricating formulation for dry running.
