High-Vacuum Rotary Feedthrough Design & Engineering

The contract calls for precision mechanical design of dual concentric rotary feedthroughs engineered for ultra-high vacuum environments, incorporating vacuum sealing, shaft isolation, and integrated motor systems to ensure reliable operation under extreme conditions. The design must maintain structural integrity and rotational precision while preventing contaminants from entering the vacuum chamber and isolating mechanical drivetrain components from sensitive internal systems. The work is classified as a subcontract under NAICS code 541330 for engineering services and is issued by the NASA Shared Services Center on behalf of the National Aeronautics and Space Administration. The solicitation was posted on July 29, 2026, with a firm response deadline of August 3, 2026. The performance location and specific point of contact are not detailed, but the technical requirements demand advanced expertise in vacuum-compatible materials, dynamic sealing technologies, and electromechanical integration for space-grade applications.
