How to read SKF NU 2222 ECJ/C3
- NU 22Series
- Cylindrical roller bearings, NU 22 series. For the same bore, each series has a different outside diameter and width.
- 22Bore
- 110 mm bore: 22 × 5.
- ECJ/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 2222 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF NU 2222 ECJ/C3 bearing has a 110 mm bore, a 200 mm outside diameter and a 53 mm width (110 x 200 x 53 mm).

SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and steel cage allows precise and durable operation in demanding industrial applications. They are ideal for machine tools, electric motors, pumps and transmission equipment. At MR Accesorios Industriales we market this line.
The designation NU … ECJ/C… is interpreted as follows: NU indicates that the bearing has two ribs on the outer ring and none on the inner ring, which allows relative axial displacement. The following number is the size code according to the dimension series. EC means it incorporates optimized-design rollers, with higher load capacity. J indicates stamped steel cage. C3 indicates an internal radial clearance greater than standard. For example, NU 206 ECJ/C3 corresponds to a bearing of series 2, with the mentioned characteristics.
These bearings are used in a wide variety of industrial applications in Argentina. They are common in electric motors, centrifugal pumps, compressors, gearboxes, machine tools and power transmission equipment. Their ability to withstand heavy radial loads and their rigidity make them suitable for environments with high mechanical demands. Industries such as food, petrochemical, steel and general manufacturing use them to ensure continuous and reliable operation.
To correctly select a cylindrical roller bearing, it is essential to consider radial load, rotation speed and environmental conditions. Assembly requires precise alignment between shaft and housing to avoid additional stresses. Proper lubrication, whether grease or oil, extends service life. Sealing will depend on the environment: in contaminated environments, additional protection is recommended. C3 radial clearance is useful when thermal expansion or interference fits are expected. Always check shaft and housing tolerances.
Regarding equivalences and interchangeability, SKF NU series bearings can be replaced by products from other manufacturers that follow the same international designation. However, it is important to verify critical dimensions and load capacities, as there may be variations in materials and treatments. To ensure full compatibility, always consult with our technical team and provide the complete code of the bearing you need to replace.

Frequently Asked Questions
- What are the dimensions of the SKF NU 2222 ECJ/C3 bearing?
- The SKF NU 2222 ECJ/C3 bearing has a 110 mm bore, a 200 mm outside diameter and a 53 mm width (110 x 200 x 53 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 2222.
- What does the C3 suffix mean in an SKF bearing?
- The C3 suffix indicates that the bearing has an internal radial clearance greater than standard. This is useful in applications where thermal expansion or interference fits are expected, as it prevents the bearing from becoming excessively preloaded.
- What is the difference between an NU and an NJ bearing?
- The NU series has two ribs on the outer ring and none on the inner ring, allowing axial displacement. The NJ series has one rib on the inner ring, which allows locating the shaft in one direction. The choice depends on axial guidance requirements.
- How should I lubricate a cylindrical roller bearing?
- Lubrication can be with grease or oil, depending on speed and operating temperature. It is important to follow the manufacturer's recommendations and maintain cleanliness to avoid contamination. Proper lubrication reduces wear and extends service life.
