Decoding NTN NU2220
- NU 22Series
- Cylindrical roller bearings, NU 22 series. Series differ in outside diameter and width even when the bore is the same.
- 20Bore
- Bore 100 mm (20 × 5).
NU 2220 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN NU2220 measures 100 mm across the bore and 180 mm across the outside diameter; its width is 46 mm (100 x 180 x 46 mm).

When equipment runs under continuous radial load, the NTN NU series cylindrical roller bearing is a common choice. Its cylindrical rollers and steel cage support demanding industrial duty. You will find these bearings in heavy machinery, gearboxes, pumps and transmission systems. MR Industrial Accessories LLC supplies this series to customers across the United States and Latin America.
Reading the NU code helps you specify the right bearing. The letters NU mean the inner ring has no flanges, so the shaft and housing can shift axially relative to each other. The numbers that follow give the size and dimensional series: NU208 is a light series bearing with a 40 mm bore, while NU10/500 is a larger size. Suffixes, when present, indicate additional features such as a brass cage, special heat treatment or internal clearance, following NTN coding.
These bearings appear in metallurgy, cement, mining and food processing plants. They are used in speed reducers, conveyor belts, mills, centrifugal pumps and machine tools. Their design handles high radial loads and resists fatigue, making them suitable for continuous operation. When axial loads are also present, they are often mounted alongside bearings that take those forces.
Selecting an NU bearing requires attention to radial load, speed and operating environment. Mounting calls for precise shaft and housing alignment plus a proper fit to prevent distortion. Grease or oil lubrication must suit the temperature and speed. In dirty conditions, add seals or oil seals for extra protection. After mounting, check internal clearance to confirm smooth running and long service life.
Cylindrical roller bearings from other brands with similar designations may be interchangeable, but always confirm dimensions, tolerances and load capacity before substituting. NTN offers many variants in the NU series, so expert advice is useful. MR Industrial Accessories LLC can help you find the right bearing for your application.

- NTN NU2220 measures 100 mm across the bore and 180 mm across the outside diameter; its width is 46 mm (100 x 180 x 46 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2220.
- What does the NU designation mean in a cylindrical roller bearing?
- NU means the inner ring has no flanges, allowing axial displacement. The following numbers define the size and dimensional series. Suffixes add details such as cage type, heat treatment or internal clearance.
- How do I choose the right NU bearing for my application?
- Consider radial load, speed, temperature and environment. Also factor in lubrication and fit. A specialist can help you select the most suitable one. Send your equipment data via WhatsApp and we'll advise you.
- Are NTN NU bearings interchangeable with other brands?
- They may be interchangeable if dimensions, tolerances and load capacity match. Always verify specifications before replacing. If you send us another brand's part number, we'll tell you the corresponding NTN equivalent.
