The History of Precision Ball Bearings
Today we use precision ball bearings for a variety of different things. Precision ball bearings help make sure that there is a high degree of control and predictability of movement. Ball bearings are the most commons means by which such friction reduction is accomplished. But it was not always this way. There was a very simple start to the precision ball bearings that we see today. Yes, before miniature bearings, roller bearings, steel ball bearings, and thrust bearings there were simply bearings. Old wooden rollers that supported objects like how precision bearings do. Some historians would say that the invention of bearings may even possibly predate the invention of the wheel. The oldest history of bearings starts with the Egyptians and how they used roller bearings.
