Cylindrical Roller Bearings FAG NJ2310 -E-M1

The FAG NJ2310 -E-M1 cylindrical roller bearing, with a 50 mm bore and a brass cage, can accommodate high radial loads as well as unilateral axial forces.

This single-row cylindrical roller bearing, the NJ2310 -E-M1 from FAG Rolling Bearings, is used in industrial applications that require a high radial load capacity. With key dimensions of a 50 mm bore, 110 mm outer diameter and 40 mm width, the design features solid flanges on the outer ring and a single-sided flange on the inner ring. This enables the bearing to function as a support bearing. The integrated brass cage guides the rolling elements in an organised manner within the roller set.

In which installation situations is the NJ2310 -E-M1 cylindrical roller bearing used?

As a support bearing, the NJ2310 -E-M1 cylindrical roller bearing is suitable for bearing arrangements subject to a predominantly radial load, where the shaft must also be guided in an axial direction. Conversely, the design allows for axial displacement of the rings relative to one another, which compensates for changes in the shaft’s length. Typical applications are found in general mechanical engineering for shaft bearings subjected to one-sided axial forces. The permissible temperature range is from –30 to +150 degrees Celsius.

What is the function of the NJ design and the brass cage?

The NJ design denotes cylindrical roller bearings with two fixed flanges on the outer ring and one flange on the inner ring. This allows the inner ring to be removed from one side, which simplifies the separate assembly of both bearing rings. For maintenance engineers and designers, this ability to dismantle the bearing facilitates installation in cases of tight fits. The brass cage guides the cylindrical rollers and is particularly suitable for demanding operating conditions involving vibrations or acceleration forces. As an open bearing, this variant requires external sealing of the housing assembly as well as a suitable lubricant supply.
