Cylindrical Roller Bearings FAG NJ328 -E-M1

The FAG NJ328 -E-M1 cylindrical roller bearing, measuring 140 x 300 x 62 mm and featuring a brass cage, offers high radial load-carrying capacity and single-sided axial guidance.

The NJ328 -E-M1 cylindrical roller bearing is a single-row radial roller bearing of the NJ design for demanding industrial applications. With dimensions of 140 mm bore, 300 mm outside diameter and 62 mm width, this roller bearing can accommodate heavy radial loads. The manufacturer, FAG, fits this version with a solid brass cage that retains its dimensional stability even under vibrations or rapid changes in rotational speed. As this is an open bearing, the lubricant can be flexibly adapted to the operating conditions.

What is the NJ328 -E-M1 cylindrical roller bearing suitable for?

This bearing is primarily used in industrial gearboxes and heavy-duty mechanical assemblies subject to high radial forces. The NJ design functions as a support bearing: it supports shafts in one axial direction whilst allowing axial displacement in the opposite direction. This allows the component to compensate for thermal expansion of the shaft within the bearing housing without any constraint. The permissible temperature range is from –30 to +150 degrees Celsius.

What are the advantages of the brass cage and the NJ design?

The designation letter M1 indicates the guided solid brass cage. Brass cages are characterised by high strength and perform well under varying speeds and in harsh environmental conditions. Furthermore, the inner ring in this design can be removed from one side. This facilitates the assembly and disassembly of the bearing rings. The bearing is manufactured to standard tolerances (P0/PN or ABEC 1) with standard radial clearance, which corresponds to common standard fits in mechanical engineering.
