What Xdot Bearing Technologies does
Xdot Bearing Technologies, also known as XDot Engineering & Analysis, was a privately held engineering firm founded in 2003 and headquartered in Charlottesville, Virginia, that specialized in foil bearing technology for high-speed turbomachinery applications. The company designed, built, and tested foil bearing solutions targeted at demanding, long-life, high-reliability use cases — principally in defense and space, energy (oil and gas, chemical processing, power generation), and chemical processing rotating equipment. Beyond its core bearing products, Xdot offered rotordynamic consulting services and rotordynamics training courses, positioning its engineering expertise as a top-of-funnel channel for industry engagement.
The firm's competitive basis was a patented foil bearing technology, supported by specialized expertise in rotordynamics and bearing build/test operations. Prior to acquisition the company operated with a small team (1–10 employees) using a direct engineering-services and niche product delivery model. In 2025, Xdot was acquired by Barber-Nichols, a Graham Corporation (NYSE: GHM) subsidiary, integrating Xdot's patented bearing technology with Barber-Nichols' engineering, manufacturing, and testing infrastructure under ISO 9001 and AS9100 quality systems. Following the acquisition, Xdot ceases to operate as an independent entity and its bearing product line is delivered through Barber-Nichols' OEM channels for defense, space, energy, and cryogenic turbomachinery applications.
