DURAMAX MARINE, LLC

DURAMAX MARINE, LLC specializes in the precision manufacturing of critical mechanical components for defense and maritime systems, with deep expertise in bearing fabrication, sealing systems, and propulsion-related hardware. The company produces sleeve bearings, stave-shaped bearings, and other high-tolerance metallic and rubber components used in guided missile propulsion units, boat propulsion systems, and marine applications. Their technical capabilities span the full lifecycle of mechanical part manufacturing—from material selection and CNC machining to quality assurance of components subjected to extreme stress, vibration, and environmental exposure. A key differentiator is their ability to deliver mission-critical parts under strict military specifications, particularly for naval and aerospace propulsion systems where reliability is non-negotiable. The contractor maintains a strong track record serving the Department of Defense and Department of Homeland Security, primarily supplying engineered components for maritime platforms, missile systems, and specialized vehicle systems. Their work supports naval vessel maintenance, aerospace propulsion integrity, and homeland security asset readiness, often through direct procurement of standardized military hardware items. Industry focus centers on NAICS 332991 (miscellaneous fabricated metal product manufacturing) and 326291 (rubber products for mechanical use), with secondary strength in 336415 (propulsion unit parts) and 336612 (boat building). This positions DURAMAX MARINE as a niche supplier of high-reliability mechanical interfaces for defense and maritime platforms, bridging metal fabrication and elastomeric sealing technologies. As a small business structured as 2K and headquartered in Hiram, Ohio, DURAMAX MARINE operates without federal certifications but maintains a focused presence in the defense supply chain. Their geographic location supports regional logistics for military and industrial customers, and their operational model emphasizes precision manufacturing agility over scale, making them a trusted source for low-volume, high-specification components.
