Cylindrical Roller Bearings FAG NJ315 -E-XL-M1-C3

FAG cylindrical roller bearing nj315-e-xl-m1-c3 with a brass cage and slightly increased radial clearance for industrial applications subject to thermal and mechanical stress.

The NJ315-E-XL-M1-C3 cylindrical roller bearing from FAG Rolling Bearings is designed as an open bearing for high radial loads. The cylindrical bore allows the inner ring to be mounted directly onto the shaft. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring, enabling axial forces to be accommodated in one direction. With an outer diameter of 160 mm and a width of 37 mm, the bearing is suitable for heavily loaded bearing arrangements in mechanical engineering.

In which applications does the NJ315-E-XL-M1-C3 cylindrical roller bearing prove its worth?

This cylindrical roller bearing is used in powertrains, gearboxes and heavy-duty industrial units where strong radial forces act on the shaft. As the bearing is of an open design, it is lubricated directly via the oil or grease circuit of the surrounding structure. The brass cage guides the rollers stably even under dynamic loads. For operating environments with temperatures ranging from –30 to +150 °C, the open design offers thermal stability during continuous industrial operation.

What advantages do the brass cage and C3 bearing clearance offer with this bearing?

The designation C3 stands for a slightly increased radial bearing clearance, i.e. greater radial play in the initial state. This clearance compensates for operational heating or tight fits without the rolling elements becoming jammed. The brass cage dampens mechanical vibrations and is also suitable for demanding lubricants. When designing the assembly, ensure a suitable external seal is incorporated, as otherwise dirt particles can penetrate the open rolling bearing unhindered.
