How to read NTN NU2213
- NU 22Series
- Cylindrical roller bearings, NU 22 series. For the same bore, each series has a different outside diameter and width.
- 13Bore
- 65 mm bore: 13 × 5.
NU 2213 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

The NTN NU series cylindrical roller bearing is a component with high radial load capacity, designed to withstand high loads and considerable speeds. Its construction with cylindrical rollers and steel cage allows precise operation in demanding industrial applications. It is used in heavy machinery, gearboxes, pumps and transmission equipment, where reliability and durability are key. MR Accesorios Industriales sells this series.
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 numbers that follow indicate the size and dimensional series; for example, NU208 corresponds to a light series bearing with a 40 mm bore, while NU10/500 indicates a larger size. Suffixes, when they appear, specify additional features such as brass cage, special heat treatment or internal clearance, according to NTN coding.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, cement, mining and food. They are found in speed reducers, conveyor belts, mills, centrifugal pumps and machine tools. Their ability to withstand high radial loads and their fatigue resistance make them suitable for continuous duty regimes. In applications with combined loads, they are usually mounted together with other types of bearings that absorb axial loads.
To correctly select an NU bearing, it is essential to consider the radial load, the rotation speed and the environmental conditions. Mounting requires precise alignment between shaft and housing, and a suitable fit to avoid deformation. Lubrication, whether with grease or oil, must be chosen according to temperature and speed; in contaminated environments, additional protection with seals or oil seals is recommended. Internal clearance must be checked after mounting to ensure smooth operation and a long service life.
Regarding equivalences, cylindrical roller bearings from other brands with similar designations may be interchangeable, but it is essential to verify dimensions, tolerances and load capacity before replacing. NTN offers a wide range of variants within the NU series, so it is always advisable to consult a specialist. MR Accesorios Industriales can advise you to find the right bearing for your specific application.
