How to read SKF NU 2224 ECML
- NU 22Series
- Cylindrical roller bearings, NU 22 series. For the same bore, each series has a different outside diameter and width.
- 24Bore
- 120 mm bore: 24 × 5.
- ECMLSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 2224 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

The SKF cylindrical roller bearing of the NU..ECML series is a component designed to withstand high radial loads and high speeds. Its separable design and the ability to align the rollers with the shaft make it ideal for demanding industrial applications. MR Accesorios Industriales sells this line as part of its broad catalog of SKF bearings, offering technical advice to select the right size.
The designation NU … ECML is interpreted as follows: NU indicates that the bearing has one row of cylindrical rollers and that the inner ring has no flanges, which allows relative axial displacement between shaft and housing. The number that follows (for example, 206, 208, 228, etc.) corresponds to the size and dimension series. The suffix EC indicates an optimized design with higher load capacity, while ML identifies the machined brass cage, suitable for high speeds and temperatures. Examples such as NU 206 ECML or NU 240 ECML show the variety of available sizes.
These bearings are used in a wide range of industrial applications in Argentina, such as gearboxes, electric motors, pumps, compressors, machine tools and mining equipment. Their ability to withstand heavy radial loads and run at high revolutions makes them suitable for power transmissions, industrial fans and rolling mill rolls. In the food and pharmaceutical sector, they are used in conveyors and mixers where cleanliness and durability are required.
To correctly select an NU..ECML bearing, take into account the radial load, the rotation speed and the environmental conditions. It is essential to check the alignment of the shaft and the housing to avoid additional stresses. Proper lubrication, whether grease or oil, extends service life; in applications with contaminants, choose additional seals or protections. Mounting must be carried out with appropriate tools, avoiding direct blows on the rollers. The machined brass cage tolerates high temperatures and speeds better.
Regarding equivalences and interchangeability, SKF bearings of the NU..ECML series can be replaced by products from other manufacturers that follow the same international designation. However, it is important to check the tolerances and internal clearance, as they may vary between brands. Standard interchangeability is based on the main dimensions (bore, outer diameter and width) and on the load capacity. Always consult the technical specifications before replacing a bearing to ensure optimum performance.

Frequently Asked Questions
- What are the dimensions of the SKF NU 2224 ECML bearing?
- The SKF NU 2224 ECML bearing has a 120 mm bore, a 215 mm outside diameter and a 58 mm width (120 x 215 x 58 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 2224.
- What does the ECML suffix mean on an SKF bearing?
- EC indicates an optimized design with higher load capacity and ML refers to the machined brass cage, which allows high speeds and withstands elevated temperatures. These suffixes are part of the standard SKF designation.
- Does this bearing allow axial displacement?
- Yes, the NU series has the inner ring without flanges, which allows relative axial displacement between the shaft and the housing. This is useful in applications where there is thermal expansion or a need for axial freedom.
- How do I know which NU bearing size I need?
- The size is determined by the required bore, outer diameter and width. Send the complete code or the dimensions of your application and at MR Accesorios Industriales we will help you select the right bearing.
