SKF steel balls from the RB line are precision rolling elements used in bearings, valves, mechanisms and devices requiring 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 3 mm diameter ball with grade G10, while RB-7.144/G10 has 7.144 mm and the same grade. The suffix G10 or G16 refers to 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 requiring smooth and repeatable movement. 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 bearing, the precision grade compatible with the clearance and operating speed, and the material and surface treatment according to the environment. Mounting must be done cleanly, avoiding impacts that alter sphericity. Lubrication and raceway alignment 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 from 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, tolerance and material before replacing. At MR Accesorios Industriales we sell this line as a brand, and we can advise you on equivalence with other references.
