Cylindrical Roller Bearings FAG NU2210 -E-XL-M1A-C3

The FAG NU2210 -E-XL-M1A-C3 cylindrical roller bearing, with a 50 mm bore and a brass cage, provides a robust floating bearing arrangement for high radial forces.

The NU2210 -E-XL-M1A-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG for industrial applications involving purely radial load carrying. Thanks to the line contact between the roller bodies and raceways, the cylindrical design can accommodate considerable radial loads. The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which significantly simplifies separate installation and subsequent inspection work at the bearing location.

What is the NU2210 -E-XL-M1A-C3 cylindrical roller bearing suitable for?

As a floating bearing, the design compensates for axial displacement of the shaft directly within the bearing without any constraint. It is particularly suitable for use with longer shafts where thermal linear expansion must not lead to additional axial stresses. Thanks to the externally mounted solid brass cage, the roller bearing is also suitable for demanding environmental conditions involving vibrations or rapid changes in rotational speed. The permissible operating temperature range extends from –30 to +150 degrees Celsius.

What are the key features of the brass cage with C3 clearance?

The solid brass cage provides stable guidance for the cylindrical rollers and is insensitive to dynamic mass forces. In combination with the slightly increased radial clearance (C3), the bearing counteracts premature stress build-up should temperature differences arise between the shaft and the housing during operation. As this is an open bearing without a groove or lubrication bore in the outer ring, an external seal for the bearing housing and a suitable lubricant supply must be provided as part of the design.
