The steel balls we handle are top quality and are extremely precise. The typical product is the ball bearing and they are used for industrial equipment, transfer equipment, and rotor area.
Other than revolving objects, ball bulb and automatic air bag equipment are the products that utilize high sphericity.
Its are all around us in our daily life even though we often aren't aware of it. |

Types of Steel Balls |
 |
|
◆Bearing steel balls (chrome steel balls)
For the material of the bearing steel balls, we use the high carbon high chrome steel (JIS G 4805 SUJ-2) which has high friction resistance. |

|
◆Carbon steel balls
It is called carbon steel ball for bicycles by the JIS standard. SWRCM10 or SWRCM12 of JIS G 3505 and JIS G 4051SCK is used for the material.
We use a vacuum carbonitriding process to increase the surface hardness and manufacture carbon steel balls. |
