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.

Ball Bearings - an overview | ScienceDirect Topics

Bearings. Ball bearings have evolved to a high state of perfection and are attractive from the standpoints of low friction loss and modest lube system demands. Roller bearings have higher capacity than ball bearings, but are not well suited for high speeds due to a tendency of the rollers to skew in operation.
