Cylindrical Roller Bearings FAG NJ2313 -E-XL-M1-C3

The FAG NJ2313 -E-XL-M1-C3 cylindrical roller bearing, featuring a brass cage and C3 clearance, provides a high-load-capacity radial bearing with dimensions of 65 x 140 x 48 mm.

This single-row cylindrical roller bearing, model NJ2313 -E-XL-M1-C3 from FAG, is designed for industrial applications where high radial forces act on the shaft. Thanks to the line contact between the cylindrical rollers and the raceways, the design can accommodate high radial loads. As an open rolling bearing, this version is manufactured without seals and can be flexibly integrated into existing lubrication systems using lubricating oil or grease.

What characteristics distinguish the NJ2313 -E-XL-M1-C3 cylindrical roller bearing as a support bearing?

In bearing arrangements with single-sided guidance, this design serves as a classic support bearing to accommodate radial forces and axial guidance forces from a single direction. The inner ring, which can be removed from one side, allows for a defined axial displacement of the shaft relative to the housing. At the same time, this ability to disassemble the components simplifies installation, as the inner ring and outer ring can be mounted independently of one another on the shaft and in the housing seat.

What function do the brass cage and C3 clearance fulfil in this bearing?

The solid brass cage guides the rows of rollers precisely and retains its mechanical stability even under high dynamic loads. In conjunction with the slightly increased radial clearance (C3), the roller bearing helps to compensate for operational thermal expansion of the components. This reduces thermal stresses between the inner and outer rings when temperature differences occur during operation. The permissible temperature range is from -30 to +150 degrees Celsius.
