The NSK RC series needle roller bearing is a single-row radial bearing with a steel outer ring and a guided needle cage. Its low-profile design allows it to be mounted in reduced radial spaces where a ball bearing does not fit. It is used in applications with moderate radial loads and medium speeds, such as machine tools, transmission equipment and precision mechanisms. MR Accesorios Industriales sells the NSK RC series in Buenos Aires, Argentina, and advises you on choosing the right size.
The RC series designation is read from its numeric code: the first digits indicate the shaft or bore diameter, and the following ones the outer diameter and width, according to the logic of the series. For example, RC-040708-FS corresponds to a bearing for a 4 mm shaft, 7 mm outer diameter and 8 mm width; RC-061008-FS for a 6 mm shaft, 10 mm outer diameter and 8 mm width; and so on. The FS suffix indicates that the bearing incorporates a felt seal or rubber lip on one side, which improves lubricant retention and protection against contaminants. Knowing this nomenclature allows you to quickly identify the size you need.
In Argentine industry, RC series needle roller bearings are used in a wide variety of equipment: machining machine spindles, pumps, compressors, gearboxes, conveyor belts and drive mechanisms in general. Their ability to withstand radial loads in reduced spaces makes them ideal for applications where size is critical, such as in the automotive, textile, food and packaging industries. They are also found in linear motion equipment and in joints that require low maintenance.
To correctly select an RC series needle roller bearing, take into account the shaft diameter, the radial load it must withstand and the speed and temperature conditions. The FS suffix is key when there is exposure to dust, chips or moisture, since the seal protects the raceway and extends service life. During assembly, ensure precise alignment between the shaft and the housing, and apply the lubrication recommended by the manufacturer. Avoid striking the bearing and verify that the radial clearance is suitable for your application.
Needle roller bearings are interchangeable between brands in terms of standardized dimensions, but each manufacturer may vary in cage, sealing and tolerances. If you bring a code from another brand, at MR Accesorios Industriales we tell you the compatible equivalent from the NSK RC series. We can also quote the exact size you need, even if it does not appear in the usual examples. The NSK RC series is available through our distribution network in Buenos Aires, Argentina.

Frequently Asked Questions
- What does the FS suffix mean in RC series bearings?
- The FS suffix indicates that the bearing incorporates a felt seal or rubber lip on one of its sides. This seal retains lubricant and prevents the entry of contaminants, which is ideal for environments with dust or dirt.
- How do I choose the correct size of an RC series needle roller bearing?
- You need to know the shaft diameter, the outer diameter and the width allowed by your housing. The RC designation includes these values in its code. If you are not sure, send us the measurements on WhatsApp and we will help you identify the bearing.
- Are NSK RC series bearings compatible with other brands?
- Yes, needle roller bearing dimensions usually follow international standards, so they can be interchanged between brands. However, the cage, sealing and tolerances may vary. If you have a code from another brand, we tell you the NSK equivalent.
