Cylindrical Roller Bearings FAG NU224 -E-XL-M1-C3

FAG single-row cylindrical roller bearing NU224 -E-XL-M1-C3 with a 120 mm bore, brass cage and increased C3 bearing clearance for demanding free-running applications.

The FAG NU224 -E-XL-M1-C3 cylindrical roller bearing is designed as a single-row radial roller bearing to accommodate high radial loads. Thanks to the line contact between the cylindrical rollers and the raceways, the design can withstand considerable transverse forces whilst maintaining high radial rigidity. The open design allows for flexible lubrication via the surrounding machine system and is suitable for operating temperatures ranging from –30 to +150 degrees Celsius.

What is the NU224 -E-XL-M1-C3 cylindrical roller bearing suitable for in practice?

In industrial powertrains, this rolling bearing primarily functions as a non-locating bearing. As the inner ring has no flanges and can be removed from both sides, the bearing compensates for axial length changes of the shaft relative to the housing without constraint within the bearing. Typical applications are found in general mechanical engineering for shaft mountings subject to high radial loads. This design is particularly suitable for applications where thermal expansion of the shaft must be accommodated.

What advantages do the brass cage and C3 clearance offer in this design?

The solid brass cage (designation M1) is characterised by high strength and dimensional stability, enabling it to withstand dynamic forces and vibrations. The version with C3 bearing clearance offers increased radial bearing clearance compared with the standard version. This additional clearance counteracts the straining of the rolling elements when heat builds up during operation or when tight fits on the shaft and housing reduce the bearing clearance once the bearing is installed.
