Cylindrical Roller Bearings FAG NU322 -E-M1

The FAG NU322 -E-M1 cylindrical roller bearing (110x240x50 mm) serves as a separable support bearing for withstanding high radial loads in industrial machinery.

The FAG NU322 -E-M1 cylindrical roller bearing is a single-row radial roller bearing designed for heavy loads. Thanks to the line contact between the cylindrical rollers and the raceways, this design can accommodate high radial forces. With a bore of 110 mm, an outside diameter of 240 mm and a width of 50 mm, this component is suitable for demanding shaft support applications in mechanical engineering. The model is available as an open bearing with standard radial clearance in tolerance class P0/PN or ABEC 1.

What is the NU322 -E-M1 cylindrical roller bearing suitable for?

This rolling bearing is used in industrial machinery and drive trains where purely radial loads need to be supported. The NU version has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the bearing to function purely as a non-locating bearing. Thermally induced changes in the shaft’s length can be compensated for axially within the bearing during operation, thereby preventing stress build-up in the housing.

What are the advantages of the design with a brass cage?

The version with a solid brass cage guides the cylindrical rolling elements precisely along the raceway, even under high acceleration. Brass is characterised by good damping properties and robustness. The inner ring, which can be removed from both sides, significantly facilitates assembly and maintenance, as the inner and outer rings can be pressed on separately. As the bearing is unsealed and the outer ring has no groove or lubrication bore, lubrication is provided via the housing environment using grease or oil within a temperature range of -30 to +150 degrees.
