for Automobile



As above illustration, dozens of auxiliary motors and generator are in a car.
To cope with the request for more convenience, comfort and safety, auxiliary motors are increasing. For carbon brushes which are used in these motors, together with long life and high power, sometimes lower noise condition is required, while because of the environmental stand point, "lead free" quality is required.
We have supplied wide range of automobile use and "lead free" grades.


In compliance with needs of compact, light weight and high torque starter motor, the request for carbon brush such as durability, high power and heat resistance, is becoming more severe and we continue to develop suitable grades to cope with it.
In recent years, higher voltage from 12V to 42V, has been applied and we also develop grades to overcome such severe conditions.


for Power tool
Carbon brush is used in the power tool such as drill, circular saw and grinder, etc.
These brushes are required not only to be long life but also many other requests - not to damage commutator, lower level of radio interference, to endure vibration, impact and in some cases, even electric brakes work.
We have developed various grades to meet such sever conditions and collected plenty of orders not only from domestic but also overseas market.



for Home appliance
Carbon brush is used in the electrical vacuum cleaner, juicer, mixer, hair dryer, and health apparatus etc.
Especially electrical vacuum cleaner brush which has biggest number of demand, needs to be performed in high level such as long life under high speed rotation and high efficiency. We have supplied many grades this field using the latest technique and got worldwide reputation.



for Industrial motor
The large size of industrial DC motor and generating motor need various grades and shapes, as it is important to choose suitable grades to be able to maintain good condition under the variety of different working condition.
We respond to these demand with many variety of grades using even imported materials and manufacturing technique.



for Micromotor
This brush category is used in small type of motor such as Automobile, OA equipment, quality hobby article.
We choose grades, considering brush contact drop, starting voltage and wear etc.
In many years, we have supplied plenty of this kind of brushes and wish to meet customer's request from the design to manufacturing stage with confident technology.



for Mechanical carbon
Utilizing the superior qualities of carbon materials such as self lubricity, heat resistant, chemical resistant,
well-machining, Mechanical carbon has been used in wide range of fields.
To choose its grade, it is necessary to have experienced knowledge on each enquiry.
Recently carbon materials are used for fuel pump as its commutator.
We develop many kinds of carbon materials and meet customer's requirements.



for Electrical contact
Its usage are divided into two parts - one is for switching contact (Relay, breaker etc) and the other is sliding contact (variable resistor, earth contact etc).
Carbon materials belong mainly to the latter.
It is important to have qualities - less change of contact resistance, less change of denaturation and contact surface.
We provide suitable grades using well experienced knowledge.



Current collector
This is applied to collect the current from the wiring or distribute it to the wiring.
This function is used for the automatic conveyor, playground ride, attraction facilities, elevator and electrical carrier etc.
We developed superior qualities of wear-resistant and arc-resistant and supply high quality current collector which has advantage of the long life and safe to the wiring.



Brush holder
Brush holder is important parts which are used in combination with brush holder and carbon brush.
It is essential to have clearance between brush holder and carbon brush not to cause chattering nor slugging problem of brush in the holder.
Brush holder must be designed not to cause brush slugging which is arisen from thermal expansion originated by increased temperature.



Holder assembly
We provide custom designed holder assemble base on which brush holder and brush are assembled.
Using such holder assemble, customer can reduce production cost.
