This catalog documents the origin and enduring impact of the first Kingsbury fluid‑film thrust bearing, installed at the Holtwood Hydroelectric Station in 1912. Through historical photographs and technical context, it tells the story of how Albert Kingsbury’s design solved a critical engineering problem and went on to support massive loads with virtually no wear. Recognized by the American Society of Mechanical Engineers as an International Historic Mechanical Engineering Landmark, the Holtwood bearing stands as proof that a simple, well‑engineered idea can change an industry and last for generations.
