Cylindrical Roller Bearings FAG N310 -E-XL-M1-C3

The FAG N310 -E-XL-M1-C3 cylindrical roller bearing is an open idler bearing with a brass cage and increased C3 clearance for radial loads, with dimensions of 50x110x27 mm.

The single-row cylindrical roller bearing N310 -E-XL-M1-C3 accommodates high radial forces and guides the shaft during operation. In the N design, the inner ring has two fixed flanges, whilst the outer ring is flangeless and removable on both sides. This design allows for unrestricted axial movement of the shaft relative to the housing. The open FAG bearing is suitable for a temperature range of –30 to +150 degrees and requires a suitable lubricant as well as an external sealing arrangement in the adjacent structure.

In which applications is the N310 -E-XL-M1-C3 idler bearing used?

This cylindrical roller bearing is primarily used in bearing arrangements that function purely as idler bearings and carry significant radial loads. As the outer ring has no flanges, the bearing arrangement compensates for temperature-induced changes in the length of the shaft during operation. Typical applications can be found in general mechanical engineering and in the mounting of rotating shafts. Wherever axial guidance is provided separately and thermal expansion would generate stresses in the system, this design serves to provide targeted compensation.

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

The solid brass cage (M1) guides the cylindrical rollers and is also suitable for applications involving vibrations or higher accelerations. Compared with the standard version, the bearing has an increased radial clearance in accordance with Class C3. This additional clearance prevents the rollers from jamming when tight fits or temperature differences between the inner and outer rings reduce the operating clearance. Combined with tolerance class P0/PN (ABEC 1), this provides a dimensionally stable rolling bearing for demanding industrial applications.
