KAYDON CORPORATION

Kaydon Corporation specializes in the precision manufacturing, evaluation, and overhaul of critical ball and roller bearings for defense and transportation systems, with deep expertise in bull gear assemblies used in high-performance radar and naval platforms. Their technical focus centers on the repair, inspection, and remanufacturing of mission-critical bearing components such as those found in AN/SPS-48 and SPQ-9B radar systems, as well as MK-82 ordnance mechanisms. The company demonstrates advanced capability in bearing metallurgy, precision machining, non-destructive evaluation, and adherence to military specification tolerances, ensuring operational readiness for demanding environments. Their ability to restore complex gear systems to original performance standards—often under tight turnaround requirements—positions them as a trusted provider for life-cycle sustainment of legacy and active-duty defense equipment. The Department of Defense is the contractor’s primary customer, consistently engaging Kaydon for the maintenance and restoration of naval and airborne radar bearing assemblies, indicating a long-standing relationship rooted in technical reliability and mission-critical support. A single contract with the Department of Transportation suggests ancillary expertise in supporting high-reliability transportation infrastructure, likely involving similar precision bearing applications in defense-adjacent systems. Kaydon’s core industry focus is in NAICS 332991—Ball and Roller Bearing Manufacturing—where they serve as a niche supplier of engineered bearing solutions for military-grade applications. Their specialization in bull gear systems for radar and weapons platforms establishes a distinct vertical in defense sustainment, differentiating them from general bearing manufacturers. They operate from Muskegon, Michigan, as a small business with a 2L entity structure, and while they hold no formal government certifications, their consistent performance on complex, high-stakes defense contracts underscores their credibility as a qualified industrial partner within the national security supply chain.
