Cylindrical Roller Bearings FAG NJ220 -E-M1

The FAG NJ220 -E-M1 cylindrical roller bearing, with a 100 mm bore, offers high radial load-carrying capacity as a separable support bearing.

The FAG NJ220 -E-M1 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With key dimensions of a 100 mm bore diameter, 180 mm outer diameter and 34 mm width, this design can withstand considerable radial forces. As this is an open bearing without an integrated seal, the component can be flexibly integrated into existing lubrication systems. The built-in brass cage guides the rolling elements precisely and is suitable for operating temperatures ranging from –30 to +150 degrees Celsius.

What is the NJ220 -E-M1 cylindrical roller bearing suitable for?

This design is suitable for bearing arrangements subject to high radial forces, where the shaft must be axially guided on one side. In the NJ version, the roller bearing acts as a support bearing: the inner ring has a fixed flange, whilst the outer ring is guided on both sides. This arrangement allows axial displacement of the shaft in one direction, but absorbs axial guiding forces from the opposite direction. The design without a groove or lubrication bore in the outer ring is intended for lubricant supply via the surrounding bearing housing.

What are the advantages of the brass cage in the NJ220 -E-M1?

The solid brass cage offers high dimensional stability under high accelerations, vibrations and shock loads. Furthermore, the material properties typical of brass reduce friction on the rollers. When designing the assembly, please note that the inner ring can be removed from one side. This feature considerably facilitates installation and removal, but requires precise alignment of the shaft axis. The bearing is manufactured with standard radial clearance and complies with the standard tolerances according to P0/PN or ABEC 1.
