For machinery that carries heavy radial loads at moderate speeds, the SKF NUB ECJ cylindrical roller bearing is a common choice. Its inner ring includes a rib, so an HJ locating ring can be added for axial guidance. The stamped steel cage keeps the rolling elements properly spaced, which supports dependable operation in tough industrial settings.
Reading the code helps you confirm what you are ordering. NUB means a cylindrical roller bearing with a rib on the inner ring, ready for an HJ locating ring. EC points to the optimized design with a stamped steel cage, and J tells you the cage is riveted. In a reference such as NUB 222 ECJ, the 222 covers the bore diameter and the dimensional series. Together, these suffixes describe a bearing built for heavy radial duty.
These bearings show up in gearboxes, centrifugal pumps, industrial fans, machine tools, conveyors and mills. Steel plants, cement plants, paper mills and food processing operations also rely on them because they handle substantial radial forces. When you are choosing one, look at the radial load, the rotational speed and the surrounding conditions. Check shaft and housing tolerances and make sure alignment is accurate, since misalignment can introduce unwanted axial loads. Lubricant selection should match temperature and speed, and the sealing arrangement needs to keep contamination out. Use the right tools during mounting to protect the rollers and cage.
If you are replacing an SKF NUB ECJ bearing, equivalents from other manufacturers that use the same international designation can often be used. Confirm the bore, outer diameter and width, along with the load characteristics, before substituting. When those specifications line up, interchange is usually possible, but it is wise to have a specialist review the application.

Frequently asked questions
- What does the NUB ECJ code indicate on an SKF bearing?
- NUB identifies a cylindrical roller bearing with a rib on the inner ring for an HJ ring. EC refers to the optimized stamped steel cage, and J means the cage is riveted. This design handles high radial loads.
- Where is the NUB 222 ECJ bearing typically used?
- It appears in gearboxes, pumps, fans, machine tools and conveyors. Because it takes high radial loads at moderate speeds, it is also found in steel, cement and paper plants.
- How should an NUB ECJ cylindrical roller bearing be mounted?
- Check alignment and the tolerances of the shaft and housing. Use suitable tools to avoid damaging the bearing. Lubricate for the operating conditions and seal properly against contamination. Contact us on WhatsApp for further details.
