SCOPE This Japanese Industrial Standard specifies the high carbon chromium bearing steels hereafter referred to as the “steels” to be used for rolling bearings.

The applicable standards of this standard are given in attached table Steel Grades and Symbol The steels shall be classified into five categories and their symbols shall be as given in Table 1. Chemical Jls The steels shall be tested in accordance with The steels shall not contain mire than 0. The wire rods, however, jus not contain more than 0. Elements not quoted in Table 2 may be added with a maximum of 0.

When a product analysis is carried out in accordance with Shape, Dimensions and Tolerances 4.

Over 2 up to and incl. Over 15 up to and incl. Over 7 up iis and incl. Over 25 up to and incl.

Remark The cold-drawn wires shall be those having a round cross section. Over 35 up to and incl. Over 50 up to and incl. Over 80 up jls and incl. Over up to and incl. In the case of round bars for forging, they shall be practically straight.

Allowable Limits of Depth of Flaws Unit: Over 25 up to and incl max. The allowable limit of flaws which are left after removal shall be agreed between the purchaser and supplier Other The allowable imperfections without repairing and limited jos of surface imperfections for the steels other than those specified in and shall be agreed between the purchaser and supplier.

Total Decarburized Depth Spheroidized round bars for maching hot-rolled round bars and cold-drawn steels shall be tested in accordance jls For the steels other than those specified in Table 8 and Table 9, the allowable limits of the total decarburized depth shall be agreed between the purchaser and supplier.

Over 7 up to and incl max. Over 15 up to and incl max. Over 15 up to and 0. The hardness of cold-drawn steels and that of low-temperature annealed steels for forging shall be agreed upon between the purchaser and supplier.

Microstructure When specified by the purchaser, the microstructure of steel shall be examined in accordance with The level of structure shall be agreed between the purchaser and supplier.

Macrostructure When specified by the purchaser, the macrostructure of steel shall be examined in accordance with The macrostructure shall be free from defects such as pipes, hair cracks, forging cracks caused by lack of deformability and blow holes, and also excessive segregations, dendrites, pits and porosity.

Non-metallic Inclusions The steels shall be examined in accordance with Macro-Streak-Flaws The steels shall be tested in accordance with The steels, however, shall be free from any macro-streak-flaw longer than 4. Method of Manufacture The method of manufacture of the steels shall be as follows 1 The steels shall be made of killed steel which is applied vacuum degassing to the molten metal or the killed steel produced by the process agreed upon between the purchaser and supplier. Sampling Method for Specimens and Number of Test Pieces Name of test Sampling method for specimens and number of test pieces Determination of total decarburized Each one test piece shall be taken from each of two or more pieces from one lot of steels of the same heat rolled or forged to the depth, Hardness test, Microstructure same diameter group 2 under the same annealing conditions, in the case of a batch furnace, and one test piece from each of two test 1 Non-metallic inclusion test, Macro-streak-flaw test, Macrostructure test 1 or more pieces from every 20 t or fracture thereof in the case of a continuous furnace.

Each one test piece shall be taken from each of two or more pieces from one lot of steels of the same heat rolled to or forged to the same diameter group 2.

Notes 1 The micro-and macro structure tests shall be applied when so specified. For the hot-rolled round bars having a diameter of more than mm, it shall be agreed upon between the purchaser and supplier Hardness Test The hardness test shall be carried out as follows 1 The sampling method and the number of test pieces shall conform to Table 13 for the hot-rolled or forged steels, and shall be agreed between the purchaser and supplier for the cold-drawn steels.

For the steels having a diameter of 15mm and under, however, the cross section may be subjected to the test surface. The test of steels for forging shall be carried out in the same manner as the test of spheroidized steels Macrostructure Test The macrostructure test shall be carried out as follows 1 The sampling method and the number of test pieces shall conform to Table However, this test shall not be applied to the wire rods and steels of 15mm and under in diameter.

For steels of mm and over in diameter, the test shall be agreed upon between the purchaser and supplier. Dimensions of Step Maching Unit: Inspection The inspection shall be carried out as follows 1 The general requirements for inspection shall be as specified in JIS G 2 The chemical composition shall conform to the requirements of 3. Taking into account the usage of steels, however, a part of inspection items listed in 2 to 8 may be omitted by agreement between the purchaser and supplier.

By agreement between the purchaser and supplier, a part of the following details may be omitted. Report The report shall be in accordance with the requirements of 8.
