Loss Reduction of Rolling Bearings for Automobile

Abstract

The role of rolling bearings is to support rotational motion with low friction. Although the friction is low in rolling bearings, it does not mean that friction does not occur at all. Many rolling bearings are used in automobiles. Therefore, if it is possible to reduce the friction loss in the rolling bearings, it can contribute to reducing the fuel consumption of the automobile. In this paper, we introduce representative techniques for reducing the friction in automotive bearings.
