Cylindrical Roller Bearings FAG NJ322 -E-M1

The FAG NJ322 -E-M1 cylindrical roller bearing combines a 110 mm bore with a brass cage for high radial loads and single-sided axial support.

The FAG NJ322 -E-M1 cylindrical roller bearing is a single-row rolling bearing designed for demanding industrial drives. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the bearing can accommodate very high radial forces and also guides the shaft in an axial direction. With dimensions of a 110 mm bore, 240 mm outer diameter and 50 mm width, it serves as a robust machine component under continuous loads.

What is the NJ322 -E-M1 cylindrical roller bearing suitable for in practice?

Design engineers primarily use this design where strong radial forces occur and thermal linear expansion of the shaft needs to be compensated for. As the bearing acts as a support bearing, it allows axial displacement in one direction whilst providing support in the opposite direction. Typical areas of application include industrial applications and gearboxes subject to combined radial and single-sided axial loads. The solid brass cage withstands even severe vibrations and high acceleration forces during continuous operation.

What advantages do the NJ design and the brass cage offer during installation?

The inner ring of the bearing can be removed from one side. This feature facilitates the separate installation of the inner and outer rings in the case of separate bearing seats. The open bearing without sealing washers is designed for external lubrication systems such as oil bath or centralised lubrication and covers a temperature range from -30 to +150 degrees. The outer ring has no groove and no lubrication bore, which is why the lubricant should be supplied from the side.
