Cylindrical Roller Bearings SKF NU2224 ECJ

The SKF NU2224 ECJ cylindrical roller bearing, measuring 120x215x58 mm, offers high radial load-carrying capacity as a separable idler bearing for industrial applications.

The SKF NU2224 ECJ cylindrical roller bearing is a single-row radial roller bearing with an optimised internal design. It accommodates high radial loads and guides the shaft in the radial direction. With key dimensions of a 120 mm bore, 215 mm outside diameter and 58 mm width, this design functions purely as a non-locating bearing. As the outer ring has solid flanges, the flangeless inner ring can be removed from both sides, which simplifies installation in mechanical engineering.

How does the NU2224 ECJ cylindrical roller bearing absorb radial forces?

This radial roller bearing is specifically designed for bearing arrangements in which high radial forces act on the shaft. As a non-locating bearing, the design compensates for thermally induced changes in the shaft’s length directly within the rolling element set without any constraint. The integrated sheet steel cage guides the cylindrical rollers evenly along their raceway and enables use within a temperature range of –30 to +150 degrees Celsius.

What advantages does the removable inner ring offer during installation?

The NU design allows both bearing rings to be mounted separately onto the shaft and housing. The flangeless inner ring can be slid onto the bearing seat separately, which simplifies handling for a shaft diameter of 120 mm. As this is an open bearing without integrated seals, the lubricant and external sealing must be selected to suit the installation environment. The rolling bearing features standard radial clearance and enhanced running accuracy to tolerance class P6.
