Cylindrical Roller Bearings SKF NU315 ECP/C3

The SKF NU315 ECP/C3 cylindrical roller bearing (75x160x37 mm) accommodates high radial forces as a non-locating bearing and offers thermal reserves thanks to its C3 clearance.

The SKF NU315 ECP/C3 single-row cylindrical roller bearing features an optimised internal design. With key dimensions of a 75 mm bore, 160 mm outside diameter and 37 mm width, this design is engineered to handle high radial loads. As the inner ring has no flanges, it can be removed from either side. This facilitates the separate assembly of the inner and outer rings in complex assemblies.

In which installation situations does the NU315 ECP/C3 prove its worth as a non-locating bearing?

Design engineers primarily use this cylindrical roller bearing as a conventional non-locating bearing. The NU design compensates for axial length changes in the shaft directly within the bearing without any constraint. Thanks to the line contact of the cylindrical rollers, the design can accommodate high radial forces. Typical applications are found in general mechanical engineering in shaft mountings where radial support is required whilst allowing free axial movement of the shaft.

What properties do the ECP polyamide cage and the C3 bearing clearance offer?

The designation C3 indicates an increased radial clearance compared with the standard version. This additional clearance compensates for operational thermal expansion and tight fits without causing the rolling elements to become stressed. The integrated polyamide cage guides the rollers quietly and reduces the mass of the rolling element assembly. In combination with dimensional accuracy class P0 and running accuracy class P6, the bearing operates within a temperature range of -30 to +120 degrees.
