Abstract Rolling bearings are mechanical elements that guide the rotation while supporting the load by rolling motion of rolling elements. They are used for supporting the rotating shaft of various industrial machines and contribute to reduction of energy consumption and heat generation by reducing friction, suppression of wear and prevention of seizure. Rolling bearings have been improved in reliability and high performance by the evolution of materials and tribology technology. In this report, the progress and future prospect of rolling bearing technology is described, focusing on the birth and evolution of tapered roller bearings which has played a major role in the development of the automobile industry, taking examples of life improvement technology by material and heat treatment and friction reduction technology.
