Cylindrical Roller Bearings FAG NU218 -E-M1

The FAG NU218 -E-M1 cylindrical roller bearing is a single-row non-locating bearing with a brass cage, designed for shaft diameters of 90 mm under high radial loads.

The FAG NU218 -E-M1 cylindrical roller bearing is characterised by its high radial load capacity. As an open, single-row rolling bearing, it features a solid brass cage and the standard tolerance class P0/PN (ABEC 1). With key dimensions of a 90 mm bore, 160 mm outside diameter and 30 mm width, this design is suitable for demanding industrial applications. The outer ring has no groove or lubrication hole, which facilitates a clean fit in the housing seat.

What is the NU218 -E-M1 cylindrical roller bearing suitable for in operation?

This roller bearing is primarily used as a conventional non-locating bearing. Due to the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless. This allows the bearing to compensate for axial length changes in the shaft directly within the bearing without any forced alignment. Typical applications include industrial bearing arrangements where high radial forces are present and thermal linear expansion of the shaft must be compensated for.

What is the function of the brass cage in the NU design?

The brass cage guides the cylindrical rollers and withstands vibrations as well as high acceleration forces. Compared to sheet metal cages, brass offers greater dimensional stability under demanding operating conditions. As the bearing is designed for a temperature range of –30 to +150 degrees and has standard radial clearance, it is suitable for standard operating conditions. Because the inner ring can be removed from both sides, both rings can be fitted separately.
