Cylindrical Roller Bearings FAG NUP2308 -E-M1A

The FAG NUP2308 -E-M1A cylindrical roller bearing, measuring 40x90x33 mm, is a single-row fixed bearing offering high radial load-carrying capacity and axial guidance in both directions.

The NUP2308 -E-M1A cylindrical roller bearing from FAG Rolling Bearings is designed as a single-row rolling bearing for demanding industrial applications. Thanks to the line contact between the rolling elements and raceways, this model can withstand significant radial loads. With a bore of 40 mm, an outside diameter of 90 mm and a width of 33 mm, the design covers a permissible temperature range from –30 to +150 degrees. The open design without an integrated seal allows for direct integration into existing lubrication systems.

How does the NUP2308 -E-M1A cylindrical roller bearing absorb axial and radial forces?

The NUP design functions structurally as a fixed bearing: two fixed flanges on the outer ring, as well as one fixed flange and one loose flange disc on the inner ring, secure the shaft in both axial directions. The cylindrical rollers simultaneously absorb heavy transverse forces and guide the shaft under high radial loads. This design is suitable for bearing locations where, in addition to predominant transverse forces, axial guiding forces on both sides must be accommodated without a separate thrust bearing.

What are the advantages of the externally guided solid brass cage?

The suffix M1A denotes an externally guided solid brass cage that maintains the spacing between the roller elements even under dynamic loads. Thanks to the guidance provided by the outer ring flange, the cage remains vibration-free and dimensionally stable despite fluctuations in speed and vibrations. In combination with the standard radial bearing clearance and tolerance class P0/PN (ABEC 1), this configuration is suitable for precision shaft systems with a defined operating temperature, where lubricating oil or grease can circulate freely around the open bearing.
