Cylindrical Roller Bearings FAG NJ324 -E-M1

The FAG NJ324 -E-M1 cylindrical roller bearing, with a 120 mm bore and a brass cage, accommodates high radial loads as well as unilateral axial loads in industrial applications.

The FAG NJ324 -E-M1 cylindrical roller bearing is a single-row rolling bearing designed for industrial applications involving high radial loads. With dimensions of a 120 mm bore, 260 mm outer diameter and 55 mm width, the bearing withstands considerable forces in mechanical engineering and plant construction. Designed as an open rolling bearing, lubrication is provided by the surrounding structure. The inner ring can be removed from one side, which facilitates the separate installation of the inner and outer rings.

What is the NJ324 -E-M1 cylindrical roller bearing suitable for?

This roller bearing is used in bearing arrangements subject to high radial forces and axial guidance in one direction. The cylindrical rollers provide a high radial load capacity due to their line contact. With two fixed flanges on the outer ring and one fixed flange on the inner ring, the bearing functions as a support bearing. It absorbs axial forces in one direction, whilst compensating for axial length changes of the shaft in the opposite direction.

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

The solid brass cage of type M1 keeps the rollers in position even in the presence of vibrations and rapid changes in rotational speed. The brass alloy exhibits thermal stability within the specified temperature range of –30 to +150 degrees. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied from the side via the housing. Manufacture to tolerance class P0 (corresponding to ABEC 1) enables precise installation in standardised housing fits.
