| Abstract | Motors used in hybrid electric vehicles (HEV), electric vehicles (EV), and the like are required to be small and high-output. The downsizing of the motor brings demands for an increase in rotations to preserve motor output, and the need for higher speed in bearings is also increasing. In response to these needs, we have developed a deep groove ball bearing for high-speed rotation which adopts a dual-support type resin cage, which we will introduce in this report. |
