NU2318-E-XL-M1-C3 FAG Cylindrical Roller Bearing 90x190x64

Heavy-Duty Cylindrical Roller Bearing for High Radial Load Applications

The FAG NU2318-E-XL-M1-C3 is a premium single row cylindrical roller bearing designed for applications requiring very high radial load capacity, outstanding rigidity and reliable compensation of axial shaft displacement. With dimensions of 90x190x64 mm, this bearing incorporates X-life technology, an optimized E internal design, a solid two-piece brass cage M1 guided by the rollers, and C3 radial internal clearance for demanding operating conditions. The NU design allows free axial displacement of the shaft relative to the housing, making it an ideal non-locating bearing for industrial gearboxes, electric motors and heavy-duty machinery.

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 while supporting heavy radial loads.

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 use C3 internal clearance?

C3 clearance compensates for thermal expansion and operating conditions involving high temperatures and heavy radial loads.

What is the purpose of the M1 brass cage?

The solid two-piece brass M1 cage, guided by the rollers, provides excellent strength, stable roller guidance and reliable operation under demanding industrial conditions.

Can the NU2318-E-XL-M1-C3 carry axial loads?

The NU design is primarily intended for very high radial loads. It functions as a non-locating bearing, allowing axial shaft displacement rather than locating the shaft axially.
