Decoding SKF NU 212 ECML/C3H
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- ECML/C3HSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 212 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 212 ECML/C3H measures 60 mm across the bore and 110 mm across the outside diameter; its width is 22 mm (60 x 110 x 22 mm).

SKF NU series cylindrical roller bearings are built for equipment that combines heavy radial loading with fast rotation. The cylindrical roller and machined brass cage arrangement keeps running precision high in tough duty. You will find them in gearboxes, pumps, industrial machinery and power transmission drives. MR supplies this line and can help you confirm the right execution for your application.
Reading the code helps you order correctly. NU means the outer ring carries two ribs while the inner ring has none, so the shaft can move axially relative to the housing. The number that follows, such as 212 or 214, gives the dimensional series size. EC signals an optimized geometry with greater load capacity. ML identifies the roller-guided machined brass cage. C…H marks a special version with larger radial clearance and heat treatment for elevated temperatures. NU 212 ECML/C3H and NU 214 ECML/C3H are two examples of this combination.
These bearings suit arrangements where radial forces dominate and high stiffness is needed. Speed reducers, gearboxes, centrifugal pumps, compressors, machine tools and mining equipment are typical homes. The food, petrochemical, steel and cement industries also rely on them. Because they tolerate heavy radial loads and run at considerable speed, they fit power transmission and roller systems on production lines.
Selection should start from the radial load, the rotation speed and the surrounding conditions. The ML brass cage works well under high temperatures and severe loads. A C…H suffix gives extra radial clearance, which matters when a thermal gradient exists between the rings. Since the design is not self-aligning, mounting calls for accurate alignment and proper lubrication. Check shaft and housing fits against the load direction. Grease or oil both work, depending on speed and operating temperature.
Bearings from other makers with similar designations may serve as replacements, but dimensions, tolerances and load capacity must be checked first. Do not assume a code crosses over without confirmation. MR supplies SKF and can review interchangeability with other brands while keeping to the technical requirements of your equipment.

Frequently asked questions
- SKF NU 212 ECML/C3H bearing: what are its dimensions?
- SKF NU 212 ECML/C3H measures 60 mm across the bore and 110 mm across the outside diameter; its width is 22 mm (60 x 110 x 22 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 212.
- What does the ECML suffix mean in an SKF bearing?
- EC stands for an optimized design with higher load capacity. ML refers to the machined brass cage, roller-guided. This pairing is typical in demanding applications.
- When is a bearing with C3H radial clearance recommended?
- C3H indicates increased radial clearance and heat treatment for high temperatures. It suits cases with thermal gradients between shaft and housing, or where thermal expansion is significant.
- Are SKF NU bearings interchangeable with other brands?
- They may be interchangeable when dimensions, tolerances and load capacity match. Always verify the technical data and check with MR before replacing.
