NAICS Code 335991-02 Description (8-Digit)

Carbon Brushes Manufacturing is a subdivision of the Carbon and Graphite Product Manufacturing industry. This industry involves the production of carbon brushes, which are essential components of electric motors and generators. Carbon brushes are used to transfer electrical current between stationary and rotating parts of the motor or generator. They are made of a mixture of carbon and graphite, which provides the necessary conductivity and durability. The manufacturing process involves the production of carbon blocks, which are then cut and shaped into the desired brush size and shape. The brushes are then fitted with metal connectors and packaged for distribution.
