= Leonardo Da Vinci - Invention: Ball Bearing = = Born 1452 Died 1519 = Ball bearings are used today in a wide variety of important machines. The technological discovery and application of ball bearings into our world has aided machines by reducing the friction and wear and tear on specific components of the equipment. Ball Bearings are used in Cars, Computers, and Exercise equipment to keep the machines from wearing down over time based off of the amount of friction and force applied to them. Ball bearings are simply the substitute to take this unnecessary force and friction, and keep the machine from breaking down. Leonardo Da Vinci is credited with the first true sketch, and accurate representation of a ball bearing and how it should be used. However, a patent was not found for them until 1869. Da Vinci was not the first to discover ball bearings, but he is ultimately recognized as the first to correctly draw t hem and illustrate their proper use.
