Cylindrical Roller Bearings FAG NU322 -E-XL-M1-C3

The FAG NU322 -E-XL-M1-C3 cylindrical roller bearing, measuring 110 x 240 x 50 mm, with a brass cage and C3 clearance, offers high radial load-carrying capacity for demanding industrial applications.

The NU322 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for high radial loads. Thanks to the line contact between the rollers and raceways, the design can withstand high radial loads during operation. This open bearing has the following main dimensions: 110 mm bore, 240 mm outer diameter and 50 mm width. It is primarily installed in gearboxes, heavy-duty drive trains and industrial machinery bearings.

What functions does the NU322 -E-XL-M1-C3 cylindrical roller bearing perform as a non-locating bearing?

This cylindrical roller bearing primarily functions as a conventional idler bearing in the bearing arrangement. The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless. As a result, the bearing compensates for operational length changes in the shaft directly in the rolling element area without any forced alignment. This feature protects the bearing arrangement from unacceptable internal axial stresses, such as those arising from the thermal expansion of shafts. This design is particularly suitable for bearing arrangements subject to purely radial loads.

What advantages do the brass cage and C3 clearance offer in terms of design?

The version with the suffix M1 features a solid brass cage that guides the rollers. Brass is characterised by high strength and good emergency running properties, which is advantageous in the event of shock loads or vibrations. Furthermore, the bearing has a radial clearance class of C3. This slightly increased bearing clearance helps to ensure that the required operating clearance is maintained even with tight fits or operating temperatures between –30 and +150 degrees.
