Cylindrical Roller Bearings SKF NJ2213 ECP

The SKF NJ2213 ECP cylindrical roller bearing combines high radial load capacity with a single-sided axial guidance function, with main dimensions of 65 × 120 × 31 mm.

The NJ2213 ECP cylindrical roller bearing is a single-row roller bearing of the NJ design in the SKF Explorer series, featuring an optimised internal design. With a bore of 65 mm, an outside diameter of 120 mm and a width of 31 mm, this design is primarily intended to support very high radial loads. Thanks to two fixed flanges on the outer ring and one fixed flange on the inner ring, the bearing serves as a support bearing. It allows axial displacement in one direction and guides the shaft in the opposite direction.

In which installation situations is the NJ2213 ECP used as a support bearing?

This thrust bearing is used where high radial forces act on the bearing arrangement and, at the same time, axial displacement in one direction needs to be limited. Typical applications include bearing arrangements subject to combined radial and one-way axial loads. As the inner ring can be removed from one side, the unit can be fitted in sections. This simplifies installation and maintenance in compact housings.

What is the function of the polyamide cage and the NJ design?

The lightweight polyamide cage, identified by the suffix ECP, ensures quiet operation of the cylindrical rollers. The NJ design acts as a support bearing, absorbs unidirectional axial forces and allows for unrestricted longitudinal compensation of the shaft in the opposite direction. With standard radial bearing clearance and a running accuracy of tolerance class P6, the open version is suitable for standard operating conditions within a temperature range of -30 to +120 degrees.
