SKF steel balls of the RB line are precision rolling elements used in bearings, valves, mechanisms and devices that require low-friction movement. They are manufactured from high-quality steel and are classified according to their nominal diameter and the G precision grade, which defines dimensional and sphericity tolerances. MR Accesorios Industriales sells this line for replacement and projects in Argentine industry.

The designation of these balls combines the letters RB with a number indicating the nominal diameter in millimeters, followed by a slash and the precision grade preceded by G. For example, RB-3/G10 corresponds to a ball of 3 mm diameter with grade G10, while RB-7.144/G10 has 7.144 mm and the same grade. The suffix G10 or G16 refers to the tolerance: the lower the number, the greater the dimensional and form precision. Examples in the series include sizes such as 6 mm, 7.938 mm, 9.525 mm and 19.05 mm, always with grade G10 or G16.

These balls are used in ball bearings, in check and needle valves, in pumps, in precision mechanisms and in positioning devices. They are also used in the automotive industry, in machine tools, in measuring equipment and in applications where smooth and repeatable movement is required. In Argentina, they are common in maintenance workshops, food plants and machinery factories that need to replace rolling elements with specific sizes.

To select the right ball, take into account the nominal diameter required by the housing or the bearing, the precision grade compatible with the clearance and the operating speed, and the material and surface treatment according to the environment. Mounting must be done cleanly, avoiding blows that alter the sphericity. Lubrication and alignment of the raceways are key to avoiding premature wear. If the application requires tight tolerances, choose grades such as G10 or lower.

SKF steel balls can be interchanged with those of other manufacturers that comply with the same dimensions and precision grade, such as equivalent ISO or DIN standards. It is important to verify the diameter, the tolerance and the material before replacing. At MR Accesorios Industriales we sell this line as an official brand, and we can advise you on the equivalence with other references. We do not invent part numbers: if you have doubts, ask us with the exact measurement.

If you need steel balls for your maintenance or project, send us the part number or the measurement on WhatsApp. At MR Accesorios Industriales we quote you promptly and help you find the right option within the SKF line. We have more than 80 years of experience in the field, and our technical team is here to advise you.
