How to read SKF NU 210 ECML/C3
- NU 2Series
- Cylindrical roller bearings, NU 2 series. For the same bore, each series has a different outside diameter and width.
- 10Bore
- 50 mm bore: 10 × 5.
- ECML/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 210 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF NU 210 ECML/C3 bearing has a 50 mm bore, a 90 mm outside diameter and a 20 mm width (50 x 90 x 20 mm).

SKF NU ECML series cylindrical roller bearings are components with high radial load capacity, designed to withstand heavy loads and considerable speeds. They are used in applications requiring rigidity and precision, such as industrial machinery, electric motors and power transmission equipment. At MR Accesorios Industriales we supply this line.
The designation of these bearings 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 number that follows, for example 208, 210 or 214, corresponds to the size and dimension series. The suffixes ECML indicate an optimized design with a machined brass window cage, and C3 or C4 indicate a radial internal clearance greater than normal. Thus, a code such as NU 214 ECML/C4 combines these characteristics for specific applications.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, cement, food and petrochemical. They are common in gearboxes, centrifugal pumps, industrial fans, machine tools and conveying equipment. Their ability to withstand high radial loads and their rigidity make them suitable for gear transmissions and applications with high mechanical demands.
To correctly select an NU ECML bearing, it is essential to consider the radial load, the rotational speed and the environmental conditions. The C3 or C4 internal clearance is chosen according to the working temperature and the mounting fit. Lubrication must be adequate: grease or oil depending on speed and temperature. During mounting, precise alignment must be ensured and impacts that could damage the rollers or raceways must be avoided. Sealing will depend on external contamination; in dirty environments additional seals are recommended.
Regarding equivalences and interchangeability, SKF bearings of the NU ECML series can be replaced by products from other brands that follow the same dimensional and clearance designation. However, it is important to verify tolerances and internal design, as they may vary between manufacturers. Always consult our technical team to confirm compatibility before making a change.

Frequently Asked Questions
- What are the dimensions of the SKF NU 210 ECML/C3 bearing?
- The SKF NU 210 ECML/C3 bearing has a 50 mm bore, a 90 mm outside diameter and a 20 mm width (50 x 90 x 20 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 210.
- What does the ECML suffix mean in an NU bearing?
- The ECML suffix indicates an optimized design with higher load capacity and a machined brass window cage. This improves performance and durability in demanding applications.
- How do I choose between C3 and C4 clearance?
- C3 clearance is suitable for normal conditions with moderate temperatures. C4 is selected when higher temperatures or tighter fits are expected, which reduce internal clearance during operation.
- Can I replace an SKF NU bearing with another brand?
- Yes, as long as the dimensional designation and internal clearance match. However, verify tolerances and internal design, as they can influence performance. Consult us to confirm the equivalence.
