Cylindrical Roller Bearings FAG N314 -E-XL-M1-C3

The FAG N314 -E-XL-M1-C3 single-row cylindrical roller bearing, with dimensions of 70x150x35 mm, is capable of withstanding high radial loads whilst allowing axial displacement when used as a non-locating bearing.

The FAG N314 -E-XL-M1-C3 cylindrical roller bearing is designed as an open, single-row radial roller bearing for industrial applications. Thanks to the line contact between the cylindrical rollers and the raceways, this design can accommodate high radial loads. The brass cage guides the rolling elements in an orderly manner within the roller set, whilst the permissible temperature range of –30 to +150 degrees enables a wide variety of operating conditions in industrial bearing arrangements.

In which installation scenarios does the N314 -E-XL-M1-C3 cylindrical roller bearing function as a non-locating bearing?

Due to its design, this roller bearing functions purely as a non-locating bearing, as the flangeless outer ring can be removed from both sides. As a result, the bearing directly compensates within the bearing itself for axial length changes in the shaft caused by heating. Typical applications include shaft mountings where, in addition to high radial loads, thermal linear expansion of the structure must be compensated for. The open design requires external sealing as well as lubrication with oil or grease within the adjacent structure.

What role do the brass cage and C3 clearance play in bearing design?

The M1 version features a brass cage characterised by mechanical strength and heat resistance. In combination with the slightly increased radial bearing clearance C3, this bearing is suitable for applications with tight fits or temperature differences between the inner and outer rings. The increased bearing clearance helps to ensure that the bearing does not become stressed even under operational thermal expansion, and that the smooth running characteristics of tolerance class P0 (ABEC 1) are maintained.
