Cylindrical Roller Bearings SKF NJ2210 ECP

The SKF NJ2210 ECP cylindrical roller bearing, measuring 50x90x23 mm, offers high radial load-carrying capacity and axial guidance in one direction.

The NJ2210 ECP cylindrical roller bearing is a single-row rolling bearing in the SKF Explorer design for demanding industrial applications. Thanks to its cylindrical rollers, the design can withstand very high radial loads. The open bearing has an inner ring with a flange on one side, whilst the outer ring is flanged on both sides. This design enables the unit to function as a support bearing, guiding shafts in one axial direction and compensating for length changes in the opposite direction.

What loads can the NJ2210 ECP cylindrical roller bearing withstand when used as a support bearing?

Typical applications are found in mechanical engineering at bearing locations where heavy radial loads are present and the shaft must be axially guided on one side. As the inner ring is removable, the shaft and housing can be fitted separately. The permissible operating temperature range extends from –30 to +120 degrees Celsius, covering a wide variety of environmental conditions.

What advantages does the polyamide cage offer in this design?

The designation letter ‘P’ indicates that a polyamide cage is fitted. This material is characterised by its low weight, which reduces inertial forces during operation and promotes quiet, low-friction running. The bearing features a standard radial clearance and an optimised internal geometry. Furthermore, this design combines dimensional accuracy to Class P0 or ABEC 1 with increased running accuracy to Class P6 or ABEC 3 for precise concentricity.
