How to read SKF NU 2206 ECML/C3L
- NU 22Series
- Cylindrical roller bearings, NU 22 series. For the same bore, each series has a different outside diameter and width.
- 06Bore
- 30 mm bore: 06 × 5.
- ECML/C3LSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 2206 is the standard (ISO) basic designation: it defines the type, the series and the bore.

The SKF NU ECML series cylindrical roller bearing is a component with high radial load capacity, designed to withstand high loads and considerable speeds. Its cylindrical roller design and machined brass cage provide precise guidance and a long service life in demanding industrial applications. It is ideal for equipment where rigidity and reliability are required, such as gearboxes, pumps and process machinery. At MR Accesorios Industriales we supply it as part of our SKF bearing offering.
The designation of the NU ECML series is interpreted as follows: the NU prefix indicates a cylindrical roller bearing with two ribs on the outer ring and none on the inner ring, which allows axial displacement. The letters EC identify a high-capacity stamped steel cage, while ML indicates a one-piece machined brass cage, suitable for high speeds and temperatures. The C3L suffix, present in examples such as NU 211 ECML/C3L, NU 2205 ECML/C3L and NU 2206 ECML/C3L, indicates an internal radial clearance greater than normal (C3) and a brass cage (L). This combination is common in applications with thermal expansion or where a looser fit is required.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, cement, food and petrochemical. They are found in gearboxes, centrifugal pumps, industrial fans, machine tools and power transmission equipment. Their ability to withstand heavy radial loads and their fatigue resistance make them suitable for operation in environments with vibrations and moderate temperatures. In continuous production plants, where reliability is critical, the NU ECML series offers stable performance.
To correctly select an NU ECML bearing, it is essential to consider the radial load, rotational speed and environmental conditions. The C3L internal clearance should be chosen when thermal differences between rings or interference fits are expected. Proper lubrication, whether grease or oil, extends service life; at high speeds, circulating oil is recommended. Mounting must ensure precise alignment between shaft and housing, avoiding misalignments that generate additional loads. The machined brass cage better tolerates shocks and accelerations.
Regarding equivalents and interchangeability, cylindrical roller bearings from different manufacturers may present variations in suffix designations and internal clearances. When replacing a bearing, verify that the main dimensions (bore, outer diameter and width) match, as well as the cage type and radial clearance. Not all part numbers are directly interchangeable; always consult the technical specifications. SKF's NU ECML series is a reliable reference, but it is essential to confirm compatibility with the original equipment.

Frequently Asked Questions
- What are the dimensions of the SKF NU 2206 ECML/C3L bearing?
- The SKF NU 2206 ECML/C3L bearing has a 30 mm bore, a 62 mm outside diameter and a 20 mm width (30 x 62 x 20 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 2206.
- What does the C3L suffix mean in an NU ECML bearing?
- The C3L suffix indicates an internal radial clearance greater than normal (C3) and a machined brass cage (L). This allows compensation for thermal expansion and improves performance in applications with high speeds or variable temperatures.
- Where are NU ECML series cylindrical roller bearings used?
- They are used in gearboxes, pumps, fans, machine tools and transmission equipment. They are common in metallurgical, cement, food and petrochemical industries, where high radial load capacities and reliability are required.
- How do I request a quote for SKF NU ECML bearings?
