Every Toyo Tanso’s plant is provided with the optimum equipment and technology, and has independent production lines. We have created a system where improvements and additions are quickly performed for any problems arising in the production process.

At Toyo Tanso group, we offer an entire array of brushes, including for general industrial use, vacuum cleaners, automotive, home electronic appliances, power tool motors, electrical supply, micro motors, and more.

Toyo Tanso carbon brushes are manufactured by sintering carbon and metal powders, and hardening them with pitch and resin. Different materials produce different characteristics in terms of electrical conductivity, thermal durability, chemical resistance, and sliding properties.

Toyo Tanso’s IG, KC and TUG product series bring together the technical and development capabilities in the fields of sliding materials that have been cultivated over many years, to meet the various demands of our customers.
