Cylindrical Roller Bearings FAG NU2315 -E-M1

The FAG NU2315 -E-M1 cylindrical roller bearing, with a 75 mm bore, brass cage and idler bearing function, offers high radial load-carrying capacity for demanding industrial drives.

With the FAG NU2315 -E-M1 cylindrical roller bearing, you are choosing a single-row rolling bearing designed for heavy radial loads. Its dimensions are a 75 mm bore diameter, 160 mm outer diameter and 55 mm width. Thanks to its robust design with a brass cage, this version is suitable for environments subject to vibrations or thermal stresses. The open bearing is designed for operating temperatures ranging from -30 to +150 degrees.

What is the NU2315 -E-M1 cylindrical roller bearing suitable for in industrial plant?

This single-row cylindrical roller bearing primarily functions as a non-locating bearing in heavy-duty drive trains and industrial gearboxes. Typical applications are found in mechanical engineering, where high transverse forces act on the shaft, whilst axial forces are absorbed by a separate locating bearing. The built-in brass cage guides the rolling elements with minimal vibration. As the bearing is designed without a housing, designers prefer to integrate it into oil- or grease-lubricated housings with external seals.

What are the advantages of the removable inner ring in the NU design?

The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless and removable from both sides. This design compensates for changes in shaft length caused by thermal expansion directly within the bearing. Furthermore, the separable inner ring simplifies assembly: you mount the outer ring and inner ring separately onto the shaft and housing. With standard radial bearing clearance and tolerance class P0/PN or ABEC 1, this variant covers common fit situations in standard operation.
