SOUTHERN GEAR & MACHINE INC

Southern Gear & Machine Inc. specializes in the precision manufacturing of high-tolerance mechanical power transmission components, with deep expertise in gear design and fabrication for defense applications. The company produces critical elements such as spur gears, anti-backlash gears, gear clusters, and transmission assemblies, engineered to meet stringent military specifications for durability, load capacity, and backlash control. Their technical capabilities encompass CNC machining, heat treatment processes, gear hobbing, and quality assurance protocols compliant with defense industry standards, serving applications in armored vehicle drivetrains, naval propulsion systems, and aerospace actuation mechanisms. A key differentiator is their ability to manufacture mission-critical components from complex engineering drawings with minimal tolerances, ensuring seamless integration into high-performance mechanical systems under extreme operational conditions. The contractor’s primary customer is the Department of Defense, consistently delivering precision gear components for land, sea, and air platforms. Their work supports maintenance, repair, and overhaul programs for military vehicles, shipboard machinery, and aircraft powertrain systems, indicating a trusted role in sustaining critical defense infrastructure. Engagement patterns suggest long-term relationships with defense logistics and maintenance commands focused on sustaining legacy and modernized platforms requiring custom gear solutions. Southern Gear & Machine Inc. operates primarily within NAICS 333613, focusing on mechanical power transmission equipment manufacturing, with supplementary experience in shipbuilding and aircraft powertrain subsystems. This positions them as a niche supplier of mission-essential mechanical components within the defense industrial base, serving specialized segments requiring exacting engineering controls and low-volume, high-reliability production. As a small business structured as a 2L entity based in Miami, Florida, the company operates without federal certifications but maintains a focused presence in the defense supply chain through technical precision and consistent delivery of specialized components. Their geographic location supports access to key military logistics hubs along the southeastern U.S. coast.
