A carbon brush is a contact component for passing current between a moving part and a stationary part in motor and generator etc. We have been working on various technical issues for more than 80 years since we started development in 1933 with the aim of be first carbon brushes maker in Japan. Currently, our carbon brushes are widely adapted as genuine part in large motors and generators used to railways, power plants, steelworks, etc.
