Decoding SKF NJ 2216 ECP/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).
- ECP/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 ECP/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 series cylindrical roller bearings are built for machines that combine heavy radial loads with high running speeds. The cylindrical roller and polyamide cage arrangement supports accurate, dependable operation in tough industrial settings. MR Industrial Accessories supplies this series within its range of bearings and power transmission components.
In the NJ layout, the inner ring carries one rib while the outer ring has two, so the bearing can guide the shaft axially in a single direction. Suffixes tell you how a specific bearing is built: EC marks an optimized geometry with greater load capacity, P means the cage is polyamide, and C3 calls out radial internal clearance above the standard value. Take NJ 204 ECP/C3 as an example: it brings those features together in a 20 mm bore bearing.
You will find these bearings in gearboxes, pumps, compressors, electric motors, machine tools and mining equipment, as well as in food, petrochemical and automotive plants where uptime matters. Their capacity for heavy radial loads at speed suits power transmission lines and roller systems on production floors.
Choosing the right variant starts with the radial load, the rotation speed and the surrounding conditions. Where thermal expansion or interference fits are part of the picture, C3 clearance is the usual recommendation. Decide on sealing according to contamination risk: sealed or shielded versions make sense in dirty settings. Match the lubricant to the speed and temperature the bearing will see, and during mounting keep alignment accurate and avoid impacts that could mark the rollers or raceways.
For cross-referencing, SKF NJ series bearings can be swapped with equivalents from other makers that share the same dimensional and suffix designation, including FAG, NSK and NTN. Tolerances and radial clearance can differ from one manufacturer to another, so verify them before committing. MR Industrial Accessories offers SKF as one of the brands it supplies, backed by technical support.

Frequently asked questions
- SKF NJ 2216 ECP/C3 bearing: what are its dimensions?
- SKF NJ 2216 ECP/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 on an SKF NJ bearing?
- C3 indicates radial internal clearance above the standard value. It is chosen when high operating temperatures or mounting fits would otherwise reduce clearance and create excessive preload.
- What is the difference between the ECP and EC suffixes on SKF bearings?
- EC denotes an optimized design with higher load capacity. The P added to it means the cage is polyamide, which lowers weight and helps at high speeds. The two letters often appear together as ECP.
- Can I replace an SKF NJ bearing with one from another brand?
- Yes, provided the dimensional designation and suffixes match. FAG, NSK and NTN offer equivalents. Check tolerances and radial clearance, since these can vary. Contact us via WhatsApp for advice.
