SHAFT CURRENT SOLUTIONS, INC.

Shaft Current Solutions, Inc. specializes in the design and manufacturing of precision electrical brush assemblies and carbon-graphite components for mission-critical defense systems. Their core capabilities center on the production of high-reliability electrical grounding brushes, brush sets, and holder assemblies used in rotating machinery, particularly in military and naval applications. The company demonstrates deep expertise in materials science for conductive carbon-graphite formulations, precision machining of electrical contacts, and assembly of components requiring low friction, high current transfer, and durability under extreme operational conditions. Their technical focus includes custom engineering of brush geometries, contact pressure optimization, and compatibility with high-voltage rotating systems—ensuring consistent performance in harsh environments. This specialization in mission-essential electrical interfaces distinguishes them as a trusted supplier for niche, high-integrity components where failure is not an option. The company maintains a consistent relationship with the Department of Defense, delivering specialized electrical components for naval, aviation, and ground vehicle platforms. Their work supports propulsion systems, generator assemblies, and rotating electrical interfaces where stable current transfer is vital to operational readiness. All recent awards stem from direct DoD procurement channels, indicating a mature, repeatable engagement model with defense logistics and maintenance commands. Their primary industry focus lies in miscellaneous electrical equipment manufacturing (NAICS 335999) and carbon-graphite product manufacturing (NAICS 335991), positioning them as a niche supplier within the defense industrial base for conductive componentry. They serve the defense electronics and electromechanical systems vertical, filling a critical gap in the supply chain for specialized, low-volume, high-reliability parts. As a small business structured as a 2L entity based in Florence, Massachusetts, Shaft Current Solutions operates without federal certifications but leverages technical precision and domain-specific manufacturing know-how to compete in the defense supply chain. Their geographic location supports efficient logistics to East Coast defense hubs and naval facilities.
