Cylindrical Roller Bearings FAG NU2313 -E-XL-TVP2-C3

FAG NU2313 -E-XL-TVP2-C3 cylindrical roller bearing, dimensions 65x140x48 mm: a single-row non-locating bearing with a polyamide cage and increased C3 clearance for demanding radial loads.

The FAG NU2313 -E-XL-TVP2-C3 cylindrical roller bearing is designed as a single-row radial bearing for applications in which purely radial forces act on the shaft. As a NU-type idler bearing, the component has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which facilitates the separate assembly of both bearing rings. With key dimensions of a 65 mm bore, 140 mm outer diameter and 48 mm width, this open bearing complies with tolerance class P0/PN or ABEC 1.

What is the NU2313 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

This bearing is primarily used in bearing arrangements that must freely compensate for thermally induced length changes in the rotating shaft. As the cylindrical rollers make line contact with the raceways, this design can accommodate high radial forces. As the bearing is manufactured without a housing, lubrication is provided by the surrounding machine housing. The application range includes shaft mountings in mechanical engineering subject to purely radial loads and requiring axial displacement.

What are the advantages of the polyamide cage and the C3 clearance?

The polyamide material gives the cage elastic properties and reduces its weight compared with metal versions, which contributes to smooth running. The permissible temperature range is between –30 and +120 degrees Celsius. The increased radial clearance of class C3 serves to prevent the rolling elements from becoming jammed when significant temperature differences occur between the inner and outer rings during operation, or when tight fits on the shaft and housing reduce the radial operating clearance.
