Decoding NTN NU2234E
- NU 22Series
- Cylindrical roller bearings, NU 22 series. Series differ in outside diameter and width even when the bore is the same.
- 34Bore
- Bore 170 mm (34 × 5).
- ESuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 2234 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN NU2234E measures 170 mm across the bore and 310 mm across the outside diameter; its width is 86 mm (170 x 310 x 86 mm).

The NTN NU E series cylindrical roller bearing is built to manage high radial loads and high speeds. Its cylindrical rollers and steel cage provide precise operation in demanding industrial settings. You will find it in heavy machinery, gearboxes, pumps, and transmission equipment. MR Industrial Accessories supplies this series as part of its bearing range.
The NU E code works like this: NU means the inner ring has no flanges, so the shaft and housing can shift axially relative to each other. The E at the end points to an optimized design with greater load capacity. Part numbers such as NU220E, NU222E, NU224E, NU226E, NU228E, NU230E, NU232E, and NU234E show the size progression. The two or three middle digits give the bore diameter and dimensional series; a higher number means a larger section and more capacity.
These bearings show up in metallurgy, cement, mining, food processing, and power generation. Common spots include gearboxes, conveyor belts, mills, centrifugal pumps, and process equipment. Their radial load capacity suits rotating machinery that runs under continuous stress. MR Industrial Accessories offers them for both replacement and new projects.
When selecting an NU E bearing, check the radial load, rotation speed, and operating environment. Shaft-to-housing alignment is critical because these bearings do not compensate for angular misalignment. Grease or oil lubrication, applied correctly, helps extend service life. Sealing depends on contamination levels; in dirty conditions, add extra protection. Use the right tools during mounting to avoid damaging the rollers.
For equivalents, NTN NU E bearings can be interchanged with similar series from other brands that follow the same international designation. Still, verify tolerances and internal clearance for your application. Our specialists can help you confirm safe interchangeability. MR Industrial Accessories can guide you to the right option for your equipment.

Frequently asked questions
- NTN NU2234E bearing: what are its dimensions?
- NTN NU2234E measures 170 mm across the bore and 310 mm across the outside diameter; its width is 86 mm (170 x 310 x 86 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2234.
- What does the NU E designation mean in NTN bearings?
- NU indicates the inner ring has no flanges, allowing axial displacement. The final E means an optimized design with higher load capacity. The central numbers define size and bore diameter.
- Where are NU E cylindrical roller bearings used?
- They are used in gearboxes, pumps, conveyor belts, mills, and heavy machinery. They suit high radial loads and high speeds in industries such as metallurgy, cement, and food processing.
- How do I choose the right NU E bearing for my equipment?
- Consider radial load, speed, and environmental conditions. Check alignment and lubrication. For a precise selection, contact us with the code or measurements of your application and we will advise you.
