Cylindrical Roller Bearings FAG NUP228 -E-M1

The FAG NUP228 -E-M1 cylindrical roller bearing is a single-row fixed bearing with a brass cage, designed for shaft diameters of 140 mm under high radial loads.

The FAG NUP228 -E-M1 cylindrical roller bearing is an open, single-row rolling bearing for industrial applications involving predominantly high radial loads. With a bore of 140 mm, an outer diameter of 250 mm and a width of 42 mm, this roller bearing reliably supports heavy shaft sections. As a fixed bearing, the NUP design absorbs axial forces in both directions via two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring.

In which installation situations is the NUP228 -E-M1 cylindrical roller bearing used?

This cylindrical roller bearing is recommended for applications where high radial forces occur and axial fixation of the shaft is required at the same time. The fixed bearing design serves to limit axial displacement of the rotating components within the housing. As this is an open design without integrated seals, lubrication is provided via external lubrication with grease or oil. The outer ring is designed without a groove or lubrication bore.

What is the function of the M1 brass cage in the NUP228 cylindrical roller bearing?

The suffix M1 denotes a solid brass cage, which keeps the cylindrical rollers in the bearing at a distance and guides them. Brass is characterised by its mechanical strength and withstands high accelerations or vibrations that occur during operation. Combined with a temperature range of -30 to +150 degrees, the unit is suitable for industrial applications subject to thermal stress. It is manufactured with standard radial bearing clearance and to tolerance class P0 or ABEC 1.
