In 1940, the United States faced an unexpected crisis: the world’s precision ball bearings were controlled almost entirely by European manufacturers — many of them inside Axis territory. Aircraft, tanks, railroads, ships, and factory machines all depended on them… and America couldn’t build a war economy without bearings.
But the U.S. had something different.
Decades earlier, a German-born carriage maker named Henry Timken invented a new kind of bearing — one built not with balls, but with tapered rollers designed to handle extreme load, heat, and lateral force. What began as a solution to wagon axle failures would evolve into one of the most important industrial technologies in American history.
This film traces the rise of the Timken tapered roller bearing — from its 1898 patent, through railroad expansion, heavy industry, and military mechanization — to its decisive role in World War II and its lasting impact on global infrastructure.
This isn’t just a war story. It’s a story about engineering independence, manufacturing discipline, and how one invention helped the U.S. avoid dependence on a German-controlled global monopoly.
