What Happened to Oilite Bearings? Chrysler’s Metal Sponge That’s Still Spinning in Your Garage

#ForgottenMechanicalSecrets #MechanicalHistory #EngineeringHistory What happened to Oilite bearings, the self-lubricating metal technology Chrysler helped turn into an industrial revolution? Discover how a tiny bronze bearing filled with oil became one of the most important hidden inventions in American mechanical history—and why it’s still keeping machines running today. In the 1930s, Chrysler helped perfect Oilite bearings, a revolutionary form of self-lubricating bronze bushing made using powder metallurgy. These remarkable metal sponges could store oil inside microscopic pores, allowing machinery to operate for years with minimal maintenance. Explore the forgotten history of Chrysler's Amplex Corporation, the engineering secrets behind sintered bronze bearings, and the technology that transformed automotive manufacturing, electric motors, and household appliances. Discover how sealed ball bearings and modern polymer materials challenged Oilite, why Chrysler eventually sold its bearing business, and how this nearly forgotten invention survived long after its original manufacturer moved on. From vintage American factories to the small motors still spinning in garages today, this is the untold story of a mechanical innovation that quietly changed the industrial world.
