Learn more about Duramax bearing technology
Duramax bearings represent the latest evolution in marine bearing technology, utilizing advanced polymer materials and precision engineering to deliver superior performance in water lubricated applications.
Unlike traditional oil lubricated systems, Duramax bearings use seawater as the lubricant. The bearing material creates a thin hydrodynamic film that separates the shaft from the bearing surface, providing smooth operation with minimal friction.
The flexible bearing housing accommodates shaft deflection and misalignment, reducing installation tolerances and ensuring optimal load distribution across the bearing surface.
Duramax bearings meet and exceed international environmental regulations, making them ideal for vessels operating in sensitive marine areas and environmentally protected waters.
