The RKB NU series cylindrical roller bearing is a component designed to withstand high radial loads and considerable speeds. Its cylindrical roller and steel cage design allows precise operation in demanding industrial applications. MR Accesorios Industriales sells this line for the Argentine market, with more than 80 years of experience in industrial supplies. If you need a specific size, message us on WhatsApp with the part number and we'll quote it.
The NU series designation is interpreted as follows: the letters NU indicate a cylindrical roller bearing with two ribs on the outer ring and none on the inner ring, which allows axial displacement. Examples such as NU 10/500 or NU 10/630 show the combination of the series and the outer diameter. In these cases, the number after the slash indicates the outer diameter in millimeters. To request the exact part number, contact us on WhatsApp.
These bearings are used in a wide variety of industrial applications in Argentina, such as gearboxes, machine tools, pumps, fans and mining equipment. Their ability to withstand heavy radial loads makes them suitable for gear drives and roller systems. In the metallurgical and cement sectors, they are used in mills and crushers. MR Accesorios Industriales advises you on selecting the right bearing for your application.
For a correct selection, take into account the radial load, the rotation speed and the environmental conditions. It is essential to verify the alignment between the shaft and the housing, and to use a suitable fit to avoid deformation. Lubrication must be appropriate for the temperature and speed; following the manufacturer's instructions is recommended. Sealing will depend on the contamination present; in dirty environments, choose bearings with additional seals or shields.
When looking for equivalents, it is common to find cylindrical roller bearings from other brands with similar designations, such as SKF, FAG or NSK. Dimensional interchangeability is usually standardized, but always verify tolerances and internal clearance. If you have another brand's part number, we can quote you the RKB equivalent.

Frequently Asked Questions
- What does the NU designation mean in a cylindrical roller bearing?
- NU indicates that the bearing has two ribs on the outer ring and none on the inner ring, which allows relative axial displacement between shaft and housing. It is ideal for pure radial loads and applications where axial freedom is required.
- How do I choose the right NU bearing for my application?
- Consider the radial load, speed, temperature and environment. Verify alignment and fit. For contaminated conditions, choose variants with seals. If you have doubts, contact us on WhatsApp with your equipment data and we'll advise you.
- Do you have equivalents for other brands?
- Yes, we can quote you the RKB equivalent of bearings from other brands. Send the original part number via WhatsApp and we'll give you the corresponding reference. Dimensional interchangeability is usually standardized, but we confirm tolerances and clearance.
