Cylindrical Roller Bearings SKF NU2313 ECP/C3

The SKF NU2313 ECP/C3 cylindrical roller bearing, measuring 65x140x48 mm, provides a rigid idler bearing for high radial loads under thermal shaft expansion.

This single-row NU2313 ECP/C3 cylindrical roller bearing is designed purely as a support bearing. Thanks to two fixed flanges on the outer ring and a flangeless inner ring, the bearing compensates for axial length changes in the shaft directly in the rolling element area. The optimised internal design, in combination with cylindrical rollers, enables the bearing to accommodate very high radial loads. As this is an open rolling bearing without sealing rings, its use requires external sealing of the housing environment.

In which applications does the NU2313 ECP/C3 cylindrical roller bearing prove its worth?

The NU2313 ECP/C3 cylindrical roller bearing is primarily used where high radial forces must be supported and axial displacement of the shaft occurs. Thanks to the inner ring, which can be removed from both sides, the assembly can be fitted in sections where space is limited. The open design allows for lubrication with lubricating oil or grease via the housing, as required.

What is the function of the polyamide cage and the C3 clearance?

The ECP design features a lightweight polyamide cage, which ensures smooth running of the cylindrical rollers. Together with the increased radial clearance (C3), rotational capability is maintained even when temperature differences between the inner and outer rings cause radial expansion. The bearing accommodates radial forces only; therefore, a separate fixed bearing is required in the design to provide axial guidance for the shaft.
