The NSK NU series cylindrical roller bearing is a component designed to support high radial loads and high speeds. Its design with cylindrical rollers and parallel raceways allows linear contact that distributes the load uniformly. It is used in industrial applications requiring rigidity and precision, such as machine tools, gearboxes and transmission equipment. MR Accesorios Industriales sells this line for the Argentine market.
The designation of the NU series is interpreted as follows: the letters NU indicate that the inner ring has no flanges, which allows relative axial displacement between ring and shaft. The numbers that follow indicate the size and dimension series. In the example NU2304ET7, the suffix ET7 indicates specific cage and heat treatment characteristics. Knowing these codes helps select the right bearing for each application.
These bearings are used in a wide variety of industries in Argentina, such as metalworking, food, mining and power generation. They are present in gearboxes, pumps, compressors, industrial fans and machine tools. Their ability to support radial loads makes them ideal for equipment that operates continuously and demands high reliability.
To correctly select an NU bearing, it is essential to consider the radial load, rotation speed and environmental conditions. Mounting requires precise alignment between shaft and housing, and adequate lubrication according to the type of cage and sealing. In applications with contaminants, it is recommended to evaluate variants with additional seals or shields. The polyamide or brass cage influences high-speed behavior.
Cylindrical roller bearings of the NU series can be interchanged with those of other brands that follow the same dimensional nomenclature. When looking for a replacement, it is important to verify the main dimensions and tolerances. If you have a part number from another brand or an unidentified part, at MR we will indicate the compatible equivalence.

Frequently Asked Questions
- What does the NU series mean in a cylindrical roller bearing?
- The NU series indicates that the inner ring has no flanges, which allows relative axial displacement between the shaft and the housing. This facilitates mounting and compensates for thermal expansion. It is a common configuration in applications with high radial loads.
- How do I choose the right suffix for my application?
- The suffix indicates characteristics such as cage type, heat treatment or internal clearance. To select it, consider speed, temperature and lubrication conditions. If you have doubts, consult us with your equipment data and we will guide you.
- Can I replace an NU bearing from another brand with an NSK one?
- Yes, if the main dimensions and tolerances match. Dimensional nomenclature is usually standard among manufacturers. If you send us the original part number, we will indicate the equivalent NSK reference so you can request a quote.
