Decoding SKF NU 211 ECML/C3L
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 11Bore
- Bore 55 mm (11 × 5).
- ECML/C3LSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 211 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 211 ECML/C3L measures 55 mm across the bore and 100 mm across the outside diameter; its width is 21 mm (55 x 100 x 21 mm).

The SKF NU ECML series is a cylindrical roller bearing built to carry high radial loads at considerable speeds. Its machined brass cage provides precise roller guidance, making it a common choice for gearboxes, pumps and process machinery where rigidity and reliability matter. MR Industrial Accessories supplies this series to customers across the United States and Latin America.
Reading the designation helps you select the right variant. NU means a cylindrical roller bearing with two ribs on the outer ring and none on the inner ring, so the shaft can move axially. EC refers to a high-capacity cage, and ML to a one-piece machined brass cage suited to high speeds and temperatures. In part numbers such as NU 211 ECML/C3L, NU 2205 ECML/C3L and NU 2206 ECML/C3L, the C3L suffix combines greater-than-normal internal radial clearance (C3) with the brass cage (L). That combination is often chosen where thermal expansion occurs or a looser fit is required.
These bearings appear in metallurgy, cement, food processing and petrochemical plants, among other industries. Typical equipment includes gearboxes, centrifugal pumps, industrial fans, machine tools and power transmission drives. They handle heavy radial loads and resist fatigue in environments with vibration and moderate temperatures, which supports stable performance in continuous production.
Selection should account for radial load, rotational speed and operating conditions. Choose C3L clearance when temperature differences between rings or interference fits are expected. Grease or oil lubrication extends service life, and circulating oil is recommended at high speeds. Mounting must align shaft and housing precisely to avoid extra loads, and the machined brass cage tolerates shocks and acceleration well.
When interchanging, cylindrical roller bearings from different manufacturers can vary in suffix designations and internal clearance. Confirm that bore, outer diameter and width match, and check cage type and radial clearance. Not every part number is directly interchangeable, so review the technical specifications before replacing.

Frequently asked questions
- SKF NU 211 ECML/C3L bearing: what are its dimensions?
- SKF NU 211 ECML/C3L measures 55 mm across the bore and 100 mm across the outside diameter; its width is 21 mm (55 x 100 x 21 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 211.
- What does the C3L suffix mean on an NU ECML bearing?
- C3L indicates an internal radial clearance greater than normal (C3) and a machined brass cage (L). This helps compensate for thermal expansion and suits high speeds or variable temperatures.
- Where are NU ECML series cylindrical roller bearings used?
- They are found in gearboxes, pumps, fans, machine tools and transmission equipment, commonly in metallurgical, cement, food and petrochemical industries that require high radial load capacity and reliability.
- How do I request a quote for SKF NU ECML bearings?
