Cylindrical Roller Bearings FAG NUP2228 -E-XL-M1-C3

The FAG NUP2228 -E-XL-M1-C3 cylindrical roller bearing is a single-row fixed bearing with a brass cage, measuring 140 × 250 × 68 mm, designed for high radial loads.

The FAG NUP2228 -E-XL-M1-C3 cylindrical roller bearing, as a single-row rolling bearing, withstands high radial loads. Thanks to its NUP design, this bearing guides the shaft axially in both directions and thus acts as a fixed bearing. With main dimensions of 140 mm bore, 250 mm outside diameter and 68 mm width, this version without an integrated seal is used in lubricated housings. The solid brass cage guides the cylindrical rollers with precision.

What is the NUP2228 -E-XL-M1-C3 cylindrical roller bearing suitable for as a fixed bearing?

Design engineers primarily use this fixed bearing where, in addition to high radial forces, axial guiding forces act on both sides. The combination of an inner ring with a fixed flange and a loose flange disc serves to axially fix the shaft. Thanks to the brass cage, this design is suitable for high dynamic loads and vibrations. The permissible temperature range of –30 to +150 degrees allows for use in demanding industrial bearing arrangements.

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

The increased C3 bearing clearance compensates for thermal expansion when significant temperature differences arise between the inner and outer rings during operation. This ensures that the bearing runs without seizing, even when heated. The M1 brass cage is characterised by high mechanical stability. As this is an open bearing with no groove or lubrication bore in the outer ring, the lubricant is supplied from the bearing environment. The bearing is rated to class P0 or ABEC 1.
