Did you know the earliest bearings were made of wood? That fact comes from the latest ESC Report from the Bearing Specialists Association (BSA) Educational Services Committee (ESC).

BSA’s Brief History of Bearings says the use of a rolling element to move heavy objects dates back to Ancient Egypt.

Much later, Leonardo da Vinci, employed for a period as a hydraulic engineer serving the Duke of Milan, spent time analyzing bearings, linkages, gears and various other mechanical transmission modes. Many of his ideas are still celebrated in engineering circles.

Steel developments in the 1800s transformed bearing manufacture and use. The report also traces more recent developments in the second half of the twentieth century.
