SJC PRECISION INC.

SJC PRECISION INC. specializes in the precision manufacturing of critical aircraft components, with demonstrated expertise in producing high-tolerance brake system parts for defense aerospace applications. Their core capability centers on machining and fabrication of mission-critical retainers and auxiliary hardware to exact military specifications, ensuring performance under extreme operational conditions. The company leverages advanced CNC machining, tight-tolerance metrology, and material-specific processing techniques to deliver components that meet stringent aerospace and defense standards. Their technical focus includes brake shoe retention systems, which require precise geometric control, surface finish integrity, and material consistency—key differentiators in safety-critical flight systems. The contractor has delivered directly to the Department of Defense, providing specialized parts for aircraft braking and control subsystems. This relationship reflects a focused engagement with defense aviation maintenance and component supply chains, where reliability and traceability are paramount. Their work supports the sustainment and modernization of military aircraft fleets, indicating alignment with DoD’s logistics and readiness objectives. SJC PRECISION INC. operates primarily within NAICS 336413, which encompasses the manufacturing of non-engine aircraft parts and auxiliary equipment. This places them squarely in the defense aerospace supply chain, serving as a niche supplier of precision mechanical components for airframe and landing systems. Their market positioning is that of a specialized manufacturer rather than a systems integrator, emphasizing component-level precision over broad system integration. As a small business structured as a 2L entity based in Milpitas, California, the company maintains a lean, technically focused operational model. While no formal government certifications are listed, their ability to secure defense contracts implies adherence to AS9100 quality standards and defense supply chain protocols. Their geographic location in California’s aerospace corridor supports access to skilled labor and defense industry ecosystems, reinforcing their role as a trusted tier-two supplier in the national defense industrial base.
