Steel and Stainless Balls

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. Stainless has excellent corrosion resistance compared with steel.

Types of Steel and Stainless Balls

  • SUJ2 balls (chrome steel balls)

    SUJ2 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

    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.
  • SUS304(18Cr-8Ni)

    SUS304(18Cr-8Ni)

    It is the most popular austenite stainless steel of the stainless steels.
  • SUS316

    SUS316

    It is a steel type classified as austenite like SUS304.As a feature, it has better corrosion resistance than SUS304.
  • SUS440C

    SUS440C

    It is the hardest martensite stainless steel of all stainless steels. By thermal treatment, the hardness has been improving.
