OVERVIEW

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 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.

Swelling in sea water is virtually eliminated with our proprietary composite resin matrix. DuraBlue thermoset polymer matrix is reinforced with synthetic fibers, and contain no organic fibers that can swell in sea water. It has an absorption rate ≤0.09%.

DuraBlue stern tube bearings have been tested in Duramax in-house lab and meet the highest level of marine industry standards. They are manufactured to meet ISO 9001 standards and are approved for commercial blue water marine use by ABS.
