Cylindrical Roller Bearings FAG N313 -E-XL-M1-C3

The FAG N313 -E-XL-M1-C3 cylindrical roller bearing, with a 65 mm bore and an outer diameter of 140 mm, provides a stable floating support for high radial loads.

This single-row cylindrical roller bearing, the N313 -E-XL-M1-C3, accommodates high radial loads thanks to the line contact between the rollers and raceways. FAG manufactures this version with a solid brass cage and increased radial clearance. Designed as an open rolling bearing, the component can be flexibly integrated into existing lubrication systems. The N design is characterised by two fixed flanges on the inner ring, whilst the flangeless outer ring remains removable from both sides.

What is the N313 -E-XL-M1-C3 cylindrical roller bearing suitable for?

Designs subject to purely radial loads and axial shaft expansion constitute the main area of application for this design. As the outer ring has no flanges, the bearing arrangement allows for free-moving length compensation directly in the rolling element area. Typical applications are found in mechanical engineering in shaft guides with a non-locating bearing function. The robust brass cage withstands even high accelerations, whilst the permissible temperature range of –30 to +150 degrees covers a wide range of thermal conditions.

What are the advantages of a brass cage and C3 clearance?

The combination of the M1 designation and bearing clearance class C3 is recommended for demanding installation situations. The brass cage guides the cylindrical rollers precisely and is particularly suitable for vibrations or thermal loads. Thanks to the slightly increased radial clearance (C3), the component compensates for thermal expansion between the inner and outer rings. Furthermore, this clearance class reduces the risk of radial binding when tight fits are mounted on the shaft and housing.
