Decoding SKF NU 208 ECKP/C3
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- ECKP/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 208 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 208 ECKP/C3 measures 40 mm across the bore and 80 mm across the outside diameter; its width is 18 mm (40 x 80 x 18 mm).

For equipment that carries heavy radial loads at considerable speed, the SKF NU ECKP series cylindrical roller bearings are a common choice. Their separable design and cylindrical rollers support precise operation in demanding conditions. MR Industrial Accessories LLC supplies this series to customers across the United States, Canada, Mexico and South America. Our team can help you confirm the right variant for your application.
Reading the designation helps you select the correct bearing. The NU prefix means the inner ring has no flanges, so the shaft and housing can move axially relative to each other. The E denotes a high load capacity design, CK a stamped steel cage, and P a dimensional and running tolerance window according to standard. A C3 suffix, as in NU 206 ECKP/C3, NU 207 ECKP/C3, NU 208 ECKP/C3 and NU 210 ECKP/C3, indicates greater than standard internal radial clearance for high temperatures or interference fits.
These bearings appear in conveyor belts, mills, centrifugal pumps, industrial fans, machine tools and speed reducers. Their rigidity and radial load capacity suit food, petrochemical, steel and cement plants, and they are often found in machine tool spindles and rolling mill rolls.
Selection depends on radial load, rotational speed, environment and lubrication. Choose sealing or protection based on contamination; in dirty conditions, seals or flingers are recommended. C3 clearance is advisable when thermal expansion or tight fits are expected. During mounting, align housings precisely and avoid impacts that damage the rollers. Proper grease or oil lubrication extends service life.
For interchangeability, SKF NU ECKP bearings can be replaced by products from other manufacturers that follow similar designations, such as NU 2.. ECKP series from other brands. Verify tolerances, internal clearance and load capacities before replacing, because small differences can affect performance. Share the complete part number and operating conditions with our technical team to confirm compatibility.

Frequently asked questions
- SKF NU 208 ECKP/C3 bearing: what are its dimensions?
- SKF NU 208 ECKP/C3 measures 40 mm across the bore and 80 mm across the outside diameter; its width is 18 mm (40 x 80 x 18 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 208.
- What does the C3 suffix mean on an SKF NU ECKP bearing?
- C3 indicates greater than standard internal radial clearance. It is used where operating temperatures are high or mounting fits create interference, compensating for thermal expansion and preventing excessive preload.
- How does the NU series differ from other cylindrical roller bearings?
- In the NU series, the inner ring has no flanges, allowing relative axial displacement between shaft and housing. This suits applications with thermal expansion or where axial freedom is required, unlike series with flanges.
- How do I request a quote for SKF NU ECKP bearings?
- Send the complete part number, for example NU 206 ECKP/C3, and the quantity via WhatsApp or email. Our team responds promptly with the information needed to proceed.
