Cylindrical Roller Bearings FAG NJ2220 -E-XL-M1-C3

The FAG NJ2220 -E-XL-M1-C3 cylindrical roller bearing offers high radial load-carrying capacity with a 100 mm bore, a brass cage and increased C3 radial clearance.

The FAG NJ2220 -E-XL-M1-C3 cylindrical roller bearing, as a single-row rolling bearing, accommodates heavy radial loads. With key dimensions of a 100 mm bore, 180 mm outer diameter and 46 mm width, this component is suitable for heavily loaded shaft mountings in mechanical engineering. The open design without sealing washers allows for flexible lubrication with grease or oil within a temperature range of -30 to +150 degrees Celsius.

What is the NJ2220 -E-XL-M1-C3 cylindrical roller bearing suitable for in practice?

This bearing type is primarily used where high radial forces are present and axial shaft movements need to be compensated for at the same time. The NJ design functions as a support bearing: the inner ring has a fixed flange, whilst the opposite side is flangeless. As a result, the bearing absorbs axial forces from one direction but allows for changes in length in the opposite direction. Typical applications include bearing arrangements with single-sided axial fixation.

What properties do the brass cage and C3 bearing clearance offer in this bearing?

The brass cage (designation M1) guides the rollers precisely, even under vibrations. The slightly increased radial clearance (C3) compensates for thermal expansion that may occur due to heating during operation or as a result of interference fits on the shaft and housing. As the inner ring can be removed from one side, installation can be carried out separately. The bearings are manufactured to tolerance class P0/PN or ABEC 1.
