Advanced Water-Lubricated Bearing Systems
We are continually advancing rubber-based elastomer bearing technology, setting new performance standards in real world applications.

Advanced Bearing solutions are custom-designed for low maintenance

& high performance.
Duramax Marine bearing solutions are a result of researching the scientific fundamentals of bearing technology, then combining that research with a solid base of product application knowledge.
Duramax Marine, using innovative thinking, is continually researching and custom-engineering new rubber-polymer bearing formulations that set new performance standards in the marine industry. All our unique rubber bearing innovations are designed to deliver not only long bearing life, but to reduce shaft and liner damage in the harshest working environments.
