How to read NTN NU2240E
- NU 22Series
- Cylindrical roller bearings, NU 22 series. For the same bore, each series has a different outside diameter and width.
- 40Bore
- 200 mm bore: 40 × 5.
- ESuffix
- NTN suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 2240 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

The NTN NU E series cylindrical roller bearing is a component designed to withstand high radial loads and high speeds. Its design with cylindrical rollers and steel cage allows precise operation in demanding industrial applications. It is used in heavy machinery, gearboxes, pumps and transmission equipment. MR Accesorios Industriales sells this series with the backing of NTN, a leading bearing brand.
The NU E 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 final letter E indicates an optimized design with higher load capacity. Codes NU220E, NU222E, NU224E, NU226E, NU228E, NU230E, NU232E and NU234E are examples of the size progression, where the two or three central digits identify the bore diameter and the dimensional series. The higher the number, the larger the section and capacity.
These bearings are used in industries such as metallurgy, cement, mining, food and power generation. In Argentina, they are common in gearboxes, conveyor belts, mills, centrifugal pumps and process equipment. Their ability to withstand radial loads makes them suitable for rotating machinery subjected to continuous stresses. MR Accesorios Industriales offers them for replacement and new projects.
To correctly select an NU E bearing, take into account the radial load, rotation speed and environmental conditions. It is essential to verify the alignment between shaft and housing, since these bearings do not compensate for angular misalignment. Proper lubrication, whether with grease or oil, extends service life. Sealing will depend on the contamination present; in dirty environments, additional protections are recommended. Mounting must be carried out with suitable tools to avoid damage to the rollers.
Regarding equivalences, NTN NU E bearings can be interchanged with similar series from other brands that follow the same international designation. However, it is important to verify tolerances and internal clearance according to the application. For safe interchangeability, consult our specialists. MR Accesorios Industriales advises you to find the right option for your equipment.
