SKF NU ECKP series cylindrical roller bearings are high radial capacity components designed to withstand heavy loads and considerable speeds. Their separable design and cylindrical roller configuration allow precise operation in demanding applications. MR Accesorios Industriales carries this line as part of its SKF bearing catalog. If you need assistance selecting the right model, our technical team is available to advise you.
The NU ECKP series designation is interpreted as follows: the NU prefix indicates that the inner ring has no flanges, allowing relative axial displacement; the letter E indicates a high load capacity design; CK corresponds to a stamped steel cage; and P indicates a dimensional and running tolerance window according to standard. The C3 suffix, present in examples NU 206 ECKP/C3, NU 207 ECKP/C3, NU 208 ECKP/C3 and NU 210 ECKP/C3, indicates a greater than standard internal radial clearance, suitable for applications with high temperatures or interference fits.
These bearings are used in a wide variety of industrial equipment in Argentina, such as conveyor belts, mills, centrifugal pumps, industrial fans, machine tools and speed reducers. Their ability to withstand high radial loads and their rigidity make them suitable for demanding environments in the food, petrochemical, steel and cement industries, among others. The NU ECKP series is common in applications requiring high precision and reliability, such as machine tool spindles or rolling mill rolls.
To correctly select a bearing from this series, it is essential to consider radial load, rotational speed, environmental conditions and the type of lubrication. Sealing or protections must be chosen according to environmental contamination; in dirty environments, seals or flingers are recommended. C3 radial clearance is advisable when thermal expansion or tight fits are expected. During mounting, it is crucial to ensure precise alignment between housings and to avoid impacts that damage the rollers. Proper lubrication, whether grease or oil, extends bearing service life.
Regarding equivalences and interchangeability, SKF NU ECKP series bearings can be replaced by products from other manufacturers that follow similar designations, such as NU 2.. ECKP series from other brands. However, it is important to verify tolerances, internal clearance and load capacities before replacing a bearing, as small differences can affect performance. To ensure compatibility, always consult our technical team by providing the complete part number and operating conditions.

Frequently Asked Questions
- What are the dimensions of the SKF NU 208 ECKP/C3 bearing?
- The SKF NU 208 ECKP/C3 bearing has a 40 mm bore, a 80 mm outside diameter and a 18 mm width (40 x 80 x 18 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 208.
- What does the C3 suffix mean on an SKF NU ECKP bearing?
- The C3 suffix indicates a greater than standard internal radial clearance. It is used in applications where operating temperatures are high or when mounting fits generate interference, as it compensates for thermal expansion and prevents excessive preload.
- How does the NU series differ from other cylindrical roller bearings?
- The NU series is characterized by the inner ring having no flanges, which allows relative axial displacement between shaft and housing. This makes it suitable for applications with thermal expansion or where axial freedom is required, unlike other series with flanges.
- How do I request a quote for SKF NU ECKP bearings?
- You can request it on WhatsApp by indicating the complete bearing part number (for example, NU 206 ECKP/C3) and the required quantity. Our technical team will respond promptly with the information needed to proceed with your inquiry.
