The NU series cylindrical roller bearing is a component with high radial load capacity, designed to withstand heavy loads and considerable speeds. Its construction with cylindrical rollers and parallel raceways allows precise operation in applications requiring rigidity and durability. MR Accesorios Industriales sells this NSK series for industrial equipment in Argentina, with more than 80 years of experience in the field.
The NU series designation is interpreted as follows: the letters NU indicate that the inner ring has no flanges, which allows relative axial displacement between the shaft and the housing. The number that follows indicates the dimension series, and the W suffix indicates that the bearing incorporates a retaining ring groove in the outer ring. For example, NU313W, NU314W and NU315W share diameter series 3 and vary in bore diameter, while NU2204W belongs to series 22, of smaller section. Knowing these codes makes correct selection easier.
These bearings are used in a wide variety of industrial applications in Argentina, such as gearboxes, centrifugal pumps, compressors, machine tools and power transmission equipment. Their ability to withstand high radial loads and their suitability for high speeds make them suitable for demanding environments. Industries such as food, petrochemical, steel and mining rely on this series to ensure continuous and reliable operation.
For correct selection and mounting, take into account the type of sealing required according to the working environment: open bearings are suitable for oil or grease lubrication in closed systems, while versions with seals or shields protect against contaminants. Precise alignment between shaft and housing is essential to avoid undue axial loads. Lubrication must be appropriate for the operating speed and temperature, and internal clearance must be selected according to service conditions.
Regarding equivalences and interchangeability, NSK NU series cylindrical roller bearings can be interchanged with those of other brands that follow the same standardized designation, such as SKF, FAG or NTN, as long as dimensions and tolerances are verified. It is important to confirm the W suffix and other variants to ensure compatibility. If you have doubts, our technical team can advise you.

Frequently Asked Questions
- What does the W suffix mean in NSK NU series bearings?
- The W suffix indicates that the bearing has a retaining ring groove in the outer ring. This allows the bearing to be axially fixed in the housing by means of a snap ring, simplifying the housing design.
- How do I choose between an open NU bearing and a sealed one?
- The choice depends on the environment: if dust, moisture or particles are present, a sealed or shielded bearing is preferable. In clean environments with controlled lubrication, an open bearing is sufficient and easier to maintain.
- Can I replace an NU bearing from another brand with an NSK one?
- Yes, as long as the main dimensions, execution type and suffix match. NU series cylindrical roller bearings follow international standards, which allows interchangeability between brands. Always verify the technical specifications.
