Decoding SKF NJ 2216 ECM/C3
- NJ 22Series
- Cylindrical roller bearings, NJ 22 series. Series differ in outside diameter and width even when the bore is the same.
- 16Bore
- Bore 80 mm (16 × 5).
- ECM/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NJ 2216 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NJ 2216 ECM/C3 measures 80 mm across the bore and 140 mm across the outside diameter; its width is 33 mm (80 x 140 x 33 mm).

SKF NJ ECM/C cylindrical roller bearings are built to handle heavy radial loads at considerable speeds. The cylindrical rollers and ground raceways support precise operation and high load capacity, making these bearings a fit for machine tools, gearboxes and transmission equipment that demand rigidity and durability. MR Industrial Accessories supplies this line as part of its range of SKF bearings.
Reading the part number helps you confirm you are ordering the right bearing. NJ means a cylindrical roller bearing with one rib on the inner ring and two on the outer ring, so it can take axial loads in one direction. The digits that follow give the size and dimensional series. ECM identifies a one-piece machined brass cage guided by the rollers, a design that supports higher speeds and greater strength. C3 calls out internal radial clearance above normal, which suits interference fits or elevated operating temperatures. Take NJ 214 ECM/C3: those features come together in a bearing with a 70 mm bore.
These bearings show up across many industrial settings. You will find them in gearboxes, large electric motors, pumps, compressors, textile machines, mining and cement equipment, machine tool spindles and rolling mill rolls. Their capacity for heavy radial loads and their rigidity make them a good match for gear transmissions and other demanding systems. Food, petrochemical and steel operations rely on them to keep equipment running continuously.
Selecting an NJ ECM/C3 bearing starts with the radial and axial loads it will carry, along with rotation speed and environmental conditions. Choose C3 clearance when the shaft or housing fit is interference, because it offsets the internal clearance that the fit removes. Lubrication matters: grease or oil both work, but oil is preferred at high speeds. During assembly, align shaft and housing precisely to avoid parasitic loads. The ECM brass cage provides robust guidance, yet it needs careful handling to prevent damage.
For equivalents, SKF NJ series bearings with ECM cage and C3 clearance can be replaced by products from other manufacturers that use the same standardized designation. FAG, NSK, NTN or Timken offer bearings with similar characteristics, but confirm that the cage design and radial clearance match what your application requires. The NJ designation is common throughout the industry, though suffixes can differ. Always check the alternative manufacturer's technical specifications for dimensional and functional compatibility.

Frequently asked questions
- SKF NJ 2216 ECM/C3 bearing: what are its dimensions?
- SKF NJ 2216 ECM/C3 measures 80 mm across the bore and 140 mm across the outside diameter; its width is 33 mm (80 x 140 x 33 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NJ 2216.
- What does the C3 suffix mean in an SKF NJ bearing?
- C3 indicates internal radial clearance greater than normal. Specify it when the bearing will run with interference fits or at elevated temperatures, since those conditions reduce internal clearance and C3 compensates for the reduction.
- What is the difference between the ECM cage and other cages?
- The ECM cage is a one-piece machined brass cage guided by the rollers. It provides greater strength and allows higher speeds than stamped steel cages, making it suitable for demanding applications.
- Can I replace an SKF NJ bearing with one from another brand?
- Yes, provided the designation and characteristics match. FAG, NSK or NTN have equivalents. Verify that the cage suffix and radial clearance are the same to ensure similar performance.
