NU2320-E-XL-M1A-C4 FAG 100x215x73 Cylindrical Roller Bearing

Heavy-Duty Cylindrical Roller Bearing for High Radial Load Applications

The FAG NU2320-E-XL-M1A-C4 is a premium single row cylindrical roller bearing engineered for applications requiring exceptional radial load capacity, high rigidity and reliable compensation of axial shaft displacement. With dimensions of 100x215x73 mm, this bearing incorporates the X-life performance concept, an optimized E internal design, a two-piece solid brass M1A cage guided on the outer ring, and C4 radial internal clearance for demanding operating conditions. The NU design allows unrestricted axial movement of the shaft relative to the housing, making the bearing an ideal non-locating bearing for heavy-duty industrial drive systems operating under high loads and elevated temperatures.

Application in Industrial Systems

The FAG NU2320-E-XL-M1A-C4 is designed for heavy industrial equipment where high radial loads and thermal shaft expansion must be accommodated.

Typical applications include:

• Industrial gearboxes
• Rolling mills
• Mining equipment
• Steel processing machinery
• Electric motors
• Compressors
• Heavy-duty pumps
• Wind power equipment
• Paper manufacturing machinery
• Cement industry equipment
• Industrial power transmission systems
• OEM machinery

The NU configuration enables free axial displacement, preventing excessive internal stress caused by thermal expansion.

FAQ

What does the NU design mean?

The NU design features two ribs on the outer ring and no ribs on the inner ring, allowing free axial displacement of the shaft relative to the housing.

What is the benefit of X-life technology?

FAG X-life bearings feature optimized internal geometry and improved manufacturing quality, providing higher load capacity, longer service life and increased operational reliability.

Why does this bearing have C4 internal clearance?

C4 radial clearance compensates for thermal expansion and operating conditions involving high temperatures, heavy loads and high rotational speeds.

What is the purpose of the M1A brass cage?

The solid brass M1A cage, guided on the outer ring, provides excellent roller guidance, high mechanical strength and reliable performance in demanding industrial applications.

Can the NU2320 bearing support axial loads?

The NU design primarily supports very high radial loads. It functions as a non-locating bearing and is intended to accommodate axial shaft displacement rather than carry axial loads.
