The NTN NU series is a double row cylindrical roller bearing built for high radial loads and considerable speeds. It suits applications where precision and load capacity matter, such as heavy machinery, mining equipment and power transmission.
In the NU designation, the letters identify a cylindrical roller bearing with a flangeless inner ring, so the shaft can move axially. The numbers that follow, as in NU2226 or NU2248, set the size and load capacity under the dimension standard. Suffixes, when present, indicate cage, heat treatment or special tolerance variants. To pick the right part number, start with the application and the operating conditions.
These bearings appear in gearboxes, gear cases, mills, crushers and conveying equipment, and in cement, steel, mining and pulp operations. They handle high radial loads and elevated temperatures, which makes them a fit for demanding environments. In production plants, you will find them in rolling mill rolls, industrial fans and large machine tools.
When selecting, review radial load, rotation speed and environmental conditions. Sealing matters: in dusty or humid areas, choose configurations with seals or protective plates. Use the lubrication specified by the manufacturer, grease or oil, and mount with precise alignment to avoid extra stresses. Internal clearance and fit tolerance affect performance and service life.
Cross-brand equivalences are possible when the main dimensions and load capacity are compared. Nomenclature varies by manufacturer, but double row cylindrical roller bearings generally follow international standards. For a replacement from another brand, confirm dimensions and operating conditions. MR can help you find the equivalent NTN reference.
If you already have the part number or model, message us on WhatsApp or email and we will send a quote promptly. We can also point you to a compatible alternative or arrange custom manufacturing when needed. MR Industrial Accessories LLC supplies bearings and power transmission parts to customers across the United States and in several Latin American countries.

Frequently asked questions
- NTN NU2252 bearing: what are its dimensions?
- NTN NU2252 measures 260 mm across the bore and 480 mm across the outside diameter; its width is 130 mm (260 x 480 x 130 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2252.
- What does the NU series mean in NTN bearings?
- The NU series covers cylindrical roller bearings with a flangeless inner ring, allowing axial displacement. The following numbers indicate size and load capacity, and the designation is standardized to make the main dimensions easy to identify.
- How do I choose the right NU bearing for my application?
- Consider radial load, speed, temperature and environment. Check the required sealing and lubrication. If you have doubts, send us the part number or dimensions and we will advise you on the correct NTN reference.
- Can I replace a bearing from another brand with an NTN one?
- Yes, as long as the main dimensions and load capacity match. International standards allow interchangeability. Send us the original part number and we will indicate the NTN equivalent and provide a quote.
