Cylindrical Roller Bearings SKF NU2204 ECP

The SKF NU2204 ECP cylindrical roller bearing, measuring 20x47x18 mm, offers high radial load-carrying capacity and serves as an easy-to-install idler bearing.

The SKF NU2204 ECP cylindrical roller bearing is a single-row radial roller bearing in the Explorer design with an optimised internal structure. Thanks to the line contact between the cylindrical rollers and the raceways, this roller bearing can accommodate high radial forces. Designed as an open bearing, it can be flexibly integrated into oil- or grease-lubricated assemblies and requires external sealing via the surrounding machine housing.

In which applications does the NU2204 ECP cylindrical roller bearing handle radial loads?

The NU2204 ECP cylindrical roller bearing is primarily used where high radial forces occur at moderate to high speeds. Typical applications include industrial drives and mechanical mountings subject to high radial loads. As the outer ring has two fixed flanges whilst the inner ring is flangeless, the component functions purely as a non-locating bearing. It compensates for operational length changes in the shaft caused by thermal expansion without constraint, axially within the bearing.

What are the distinctive features of the version with a polyamide cage?

The polyamide cage (designation suffix ECP) guides the cylindrical rollers precisely and is characterised by its low weight. This choice of material reduces inertial forces and friction during operation, which minimises noise levels. Furthermore, the NU design allows for separate assembly: the inner ring can be removed from both ends and fitted separately onto the shaft before the unit is assembled with the outer ring and set of rollers. Dimensional accuracy complies with tolerance class P0/PN (ABEC 1), whilst running accuracy is manufactured to class P6 (ABEC 3).
