Product Overview

DuraBlue water-lubricated stern tube bearings are manufactured using a unique synthetic reinforced composite that incorporates solid lubricants for superior operation and outstanding wear life in blue water applications. The composite resin matrix was designed to withstand the rigors of seawater operation and frictional heat generated when used in stern tube propulsion systems.


DuraBlue Composit Bearings  is dimensionally stable, has a very low coefficient of expansion in extremely cold or tropical regions. DuraBlue is designed to tolerate edge loading and misalignment even with the heaviest loads. It is chemical and corrosion resistant and will not cause corrosion to housing.
