The 30 Most Important Leonardo da Vinci Inventions - Life …

Leonardo da Vinci invented the ball bearing between the years 1498-1500. He designed it to lower the friction between two plates that would be in contact in his other famous design, the helicopter. Although the design of the helicopter was unsuccessful, the bearing or ball bearing is a different story.

The History of Tribology | Fritsche - Hersteller Schmiertechnik - …

Da Vinci studied friction on horizontal and inclined planes as well as wear on slide bearings. The results of these investigations were the first and second friction laws of Leonardo da Vinci. In 1490, Leonardo da Vinci modified the rolling bearing by almost entirely replacing the moving coupling between the two parts with a mechanism with reduced rolling friction.

Cracking da Vinci’s Code: Understanding Friction and Friction …

Leonardo da Vinci, a tribology pioneer, first discovered the basic laws of sliding friction back in 1493. These are the four types of friction he studied: 1. Sliding. a) For example, simply rubbing your palms together is sliding friction. b) In industrial settings, we see sliding friction in Journal Bearings, Slideways, Gates, etc.

Bearing basics | SKF

Rolling bearings support and guide, with minimal friction (), rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. Rolling bearings provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.
