Cylindrical Roller Bearings FAG NU2320 -E-XL-M1-C3

The FAG NU2320 -E-XL-M1-C3 cylindrical roller bearing, measuring 100x215x73 mm, offers high radial load-carrying capacity as a separable loose bearing for demanding industrial applications.

The NU2320 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for high radial loads. With a bore of 100 mm, an outside diameter of 215 mm and a width of 73 mm, this roller bearing can withstand high transverse forces. Designed as an open bearing, it operates within a temperature range of -30 to +150 degrees and complies with tolerance class P0/PN or ABEC 1.

How does the NU design compensate for axial length changes in the shaft?

The bearing primarily absorbs high radial forces where thermal length changes in the rotating shaft need to be compensated for. In bearing arrangements with separate fixed and floating bearings, the NU design serves as the floating bearing. As the inner ring has no guide flanges, the shaft can move axially relative to the housing. This design reduces axial stresses in the bearing system caused by heat-induced shaft expansion during operation.

What are the distinctive features of the brass cage and C3 radial clearance?

The combination of a solid brass cage and a slightly increased radial clearance (C3) is designed for demanding operating conditions. The brass cage guides the cylindrical rollers precisely and withstands high accelerations and vibrations. The C3 bearing clearance compensates for thermal expansion when there is a temperature gradient between the inner and outer rings or when tight fits reduce the operating clearance. Both bearing rings are separable, which facilitates the assembly of the components.
