Cylindrical Roller Bearings SKF NJ2222 ECP

With dimensions of 110 × 200 × 53 mm, the SKF NJ2222 ECP cylindrical roller bearing combines a high radial load capacity with a single-sided axial guidance function.

This single-row NJ2222 ECP cylindrical roller bearing from SKF is designed for demanding industrial applications where heavy radial forces need to be transmitted. Designed as an open bearing, the component features an optimised internal design in the Explorer version. The interaction between the cylindrical rollers and the solid rings contributes to rigidity during operation. An external lubrication supply is recommended for installation and design, as the outer ring is manufactured without a groove or lubrication bore.

What loads can the NJ2222 ECP cylindrical roller bearing accommodate?

This rolling bearing is primarily used in bearing arrangements that are subjected to high radial forces and require axial guidance in one direction. Due to the line contact of the cylindrical rollers, the bearing accommodates high radial loads. At the same time, the NJ design allows for one-sided axial guidance of the shaft. The bearing thus acts as a support bearing and compensates for axial displacement in one direction directly in the rolling element area.

What are the advantages of the NJ design and the polyamide cage?

The NJ design is characterised by two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the inner ring to be removed from one side for assembly, which simplifies fitting onto the shaft. The integrated polyamide cage guides the rolling elements quietly and reduces the bearing’s own weight. The bearing is designed for operating temperatures ranging from -30 to +120 degrees and features the standard radial bearing clearance as well as running accuracy in accordance with tolerance class P6.
