SKF steel balls of the RB RS series are precision elements used as components in bearings, valves, pumps and mechanisms requiring rolling motion. Their polished surface and dimensional tolerance allow smooth operation and uniform load distribution. MR Accesorios Industriales sells this line for the Argentine industrial market, with technical advice to choose the appropriate size for each application.
The designation of the RB RS series is interpreted as follows: the letters RB identify the steel ball family, while the number that follows indicates the nominal diameter in millimeters. For example, RB-5 RS corresponds to a ball of 5 mm diameter, RB-6.35 RS to one of 6.35 mm (equivalent to 1/4 inch) and RB-9.525 RS to one of 9.525 mm (3/8 inch). The suffix RS indicates that the ball has a surface treatment or coating that gives it corrosion resistance, suitable for environments with humidity or moderate exposure to external agents.
These balls are used in a wide variety of industries in Argentina, such as metalworking, food, chemical and petrochemical. They are found in ball bearings, check valves, metering pumps, transport systems, machine tools and packaging equipment. They are also used as calibration elements or in positioning mechanisms. Their versatility makes them suitable for both maintenance and component manufacturing.
To select the appropriate ball, take into account the required nominal diameter, the degree of dimensional precision and the load to be supported. The RS suffix provides corrosion protection, but verify compatibility with the lubricant and the working environment. During mounting, ensure the raceways are clean and avoid impacts that could damage the surface. Lubrication must be the recommended one for the type of bearing or mechanism, and correct alignment extends the service life of the assembly.
Regarding equivalences and interchangeability, steel balls are specified by their diameter and tolerance, so they can be replaced between different brands as long as these characteristics and the material match. SKF is a globally recognized brand, and MR Accesorios Industriales sells it as part of its line of bearings and components. If you need a special size, ask us and we will advise you on the available alternatives.

Frequently Asked Questions
- What does the RS suffix mean in SKF steel balls?
- The RS suffix indicates that the ball has a surface treatment or coating that improves its corrosion resistance. This makes them suitable for environments with humidity or moderate exposure to external agents, although it is always recommended to verify compatibility with the lubricant and the specific environment.
- How do I choose the correct ball diameter?
- The diameter is selected according to the available space and the load requirements of the mechanism. The designation includes the nominal diameter in millimeters, such as 5 mm or 6.35 mm. If you have doubts, ask us with the measurements of your application and we will advise you.
- Are SKF RB RS series balls interchangeable with other brands?
- Yes, as long as the nominal diameter, dimensional tolerance and material match. Balls are specified by these characteristics, so they can be replaced between brands. To ensure compatibility, verify the technical specifications or ask us.
