Decoding SKF NJ 2212 ECM
- NJ 22Series
- Cylindrical roller bearings, NJ 22 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- ECMSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NJ 2212 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

SKF NJ ECM cylindrical roller bearings are built for rotating equipment that carries heavy radial loads at considerable speed. The cylindrical roller and cage arrangement supports precise running in tough industrial service. Typical installations include electric motors, pumps, compressors and transmission units. MR Industrial Accessories LLC supplies these bearings as part of its SKF line.
Reading the code helps you order correctly. NJ means the outer ring carries two ribs and the inner ring one, so the bearing accommodates axial movement in a single direction. The middle digits, such as 207, 208 or 209, set the size and dimension series. ECM identifies an optimized version with a single-piece machined brass cage, window-centered and guided by the rollers, intended for elevated speeds and loads. Part numbers in this family include NJ 207 ECM, NJ 208 ECM and NJ 209 ECM.
These bearings appear in metallurgy, cement, paper, mining and food processing plants. Common equipment includes large electric motors, gearboxes, centrifugal pumps, industrial fans and machine tools. Their capacity for heavy radial loads and their stiffness suit gear transmissions and positions that demand high rotational accuracy.
Selection starts with radial and axial load, operating speed and the surrounding conditions. Confirm the internal clearance that matches temperature and fits. Grease or oil both work as lubricants; the choice follows speed and temperature. Correct alignment between housing and shaft matters, and proper tooling during mounting protects rollers and raceways from damage.
Interchange with other makers that use the same standardized designation is possible, for example FAG, NSK, NTN or Timken, as long as dimensions and tolerances agree. When comparing equivalents, check the cage suffix and internal clearance, not just the base code. The MR Industrial Accessories LLC team can help you find a suitable replacement.

Frequently asked questions
- SKF NJ 2212 ECM bearing: what are its dimensions?
- SKF NJ 2212 ECM measures 60 mm across the bore and 110 mm across the outside diameter; its width is 28 mm (60 x 110 x 28 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NJ 2212.
- What does the ECM suffix mean on an NJ bearing?
- ECM indicates a one-piece machined brass cage with a centered window, guided by the rollers. This design supports high speeds and loads and improves roller guidance.
- Does this bearing support axial loads?
- It does, but in one direction only, because of the single inner ring rib and the two outer ring ribs. Axial loads in both directions call for other designs, such as an NJ with an extra ring or angular contact ball bearings.
- How do I choose the right lubricant for an NJ bearing?
- Base the choice on speed, temperature and environment. Oil suits high speeds, while grease of appropriate consistency works at moderate speeds. If water or contaminants are present, select a lubricant with the corresponding properties.
