KROBACH MFG. CORP.

KROBACH MFG. CORP. specializes in the precision manufacturing of mission-critical mechanical components for defense and industrial systems, with deep expertise in mechanical power transmission, fluid power systems, and fastener production. The company produces shafts, sprockets, rods, spacers, clevises, and threaded fasteners to exacting military specifications, serving applications in aircraft, ground vehicles, and hydraulic/pneumatic systems. Their technical capabilities include CNC machining, heat treatment, surface finishing, and tight-tolerance fabrication of components such as fluid valve stems, bearing assemblies, and gear-driven transmission elements. KROBACH’s ability to deliver custom-engineered parts for high-vibration, high-pressure environments distinguishes them as a trusted supplier of durable, field-proven hardware for demanding operational conditions. The contractor maintains a consistent relationship with the Department of Defense, supplying precision-engineered parts across multiple branches and logistics commands. Their work supports maintenance, repair, and overhaul (MRO) operations, as well as new equipment integration, with a focus on components critical to propulsion, actuation, and fluid control systems. The DLA Land and Maritime division has also engaged KROBACH for indefinite delivery contracts, indicating reliable performance in sustaining defense logistics networks. KROBACH’s industry focus centers on NAICS codes 333613 (mechanical power transmission equipment), 332912 (fluid power valve and hose fittings), and 332722 (bolts, nuts, screws, and washers), reflecting a specialization in mechanical subsystems for aerospace, armored vehicles, and heavy machinery. They serve as a niche supplier of certified mechanical interfaces and load-bearing components, positioning themselves within the defense industrial base as a fabricator of non-electronic, high-reliability hardware. As a small business structured as a 2L entity based in Hayward, California, KROBACH MFG. CORP. operates without federal certifications but maintains a focused, technically proficient presence in the defense supply chain. Their geographic proximity to major aerospace and defense hubs enhances responsiveness to urgent military procurement needs.
