For decades, Duramax Marine has worked with the U.S. Navy and allied navies, researching and testing ways to increase our water-lubricated bearing performance in combatant vessels. When performance is mission critical our bearings exceed the expectations every time. Our team of engineers and bearing specialists are available to answer any need that arises.
Duramax Johnson Cutless Sleeve and Flange bearings were the first and only bearings to meet all MIL-DTL-17901C Class II requirements. The Duramax ROMOR I Stave Bearing System was originally field tested on the Trident submarine with remarkable results. Its low coefficient of friction and wear life exceeded everyone's expectations. It experienced virtually no shaft wear, or bearing initiated hull noise. Proven technology like this is the reason why 90% of all surface ships and submarines of the U.S. Navy are running with our water-lubricated rubber stern tube bearing technology today.
Our staff's dedication to delivering the highest performing, most consistent high quality level of products to the marine industry has not only earned the trust of the U.S. Navy, but also the U.S. Coast Guard, other branches of service, law and drug enforcement, and navies around the world.

Duramax Marine is an ISO 9001: 2015 Certified Company.

We are proud to have been audited and certified by an independent ISO 9001 registrar; Smithers Quality Assessments (SQA). This certification establishes that Duramax Marine products and services are produced using a quality management system that meets internationally recognized requirements.
