Cylindrical Roller Bearings FAG NUP315 -E-XL-M1-C3

The FAG NUP315 -E-XL-M1-C3 cylindrical roller bearing, a single-row fixed bearing with a 75 mm bore, offers high radial load-carrying capacity under demanding operating conditions.

The NUP315 -E-XL-M1-C3 cylindrical roller bearing is a single-row rolling bearing designed for high mechanical loads. The NUP design functions as a fixed bearing thanks to two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. As a result, this design supports shafts in both axial directions. The brass cage guides the rolling elements with low vibration, whilst the P0/PN tolerance class ensures precise concentricity.

What is the NUP315 -E-XL-M1-C3 cylindrical roller bearing suitable for as a fixed bearing?

This design is used when bearing locations need to accommodate alternating axial forces in addition to prevailing radial forces. Thanks to its fixed bearing function, the component secures the shaft axially within the housing. Typical applications include gearboxes and industrial drives with combined load profiles. Thanks to the robust brass cage, the design is suitable for environments subject to vibrations and higher acceleration forces.

What properties do the brass cage and the C3 clearance offer?

Brass is characterised by high strength and resistance to thermal stresses. Combined with the permissible temperature range of –30 to +150 degrees, the open bearing is suitable for demanding operating environments. The increased C3 radial clearance compensates for operational thermal expansion between the shaft and the housing. An external seal and a continuous lubricant supply must be provided for operation.
