Cylindrical Roller Bearings FAG NJ319 -E-M1

FAG NJ319 -E-M1 cylindrical roller bearing: A single-row support bearing with a 95 mm bore, 200 mm outer diameter and a brass cage, designed for high radial loads.

The FAG NJ319 -E-M1 cylindrical roller bearing, as a single-row radial roller bearing, can accommodate very high radial loads. Thanks to the line contact between the rollers and raceways, this design offers high rigidity during operation. The NJ design functions as a support bearing: it supports axial forces in one direction whilst allowing axial displacement in the opposite direction. This open rolling bearing, which has no sealing washers, is suitable for oil- or grease-lubricated environments ranging from –30 to +150 degrees Celsius.

What roles does the NJ319 -E-M1 cylindrical roller bearing fulfil in industrial plant?

The NJ319 -E-M1 cylindrical roller bearing is primarily used in bearing arrangements subject to high radial forces and single-sided axial guidance. The bearing accommodates one-way axial forces and allows for axial displacement in the opposite direction to compensate for thermal length changes in the shaft. This design reduces the risk of axial stress in the bearing seat. The brass cage reliably guides the cylindrical rollers even at high speeds.

What advantages do the brass cage and the NJ design offer when selecting bearings?

The solid brass cage (M1) is characterised by high strength and good run-out properties in the event of vibrations or insufficient lubrication. Furthermore, the inner ring, which can be removed from one side, facilitates installation: you can mount the inner and outer rings separately onto the shaft and housing. The key dimensions are an inner diameter of 95 mm, an outer diameter of 200 mm and a width of 45 mm. The component complies with the standard tolerance class P0/PN or ABEC 1 and has standard radial clearance for normal operating temperatures.
