Cylindrical Roller Bearings FAG NJ2224 -E-XL-M1-C3

The FAG NJ2224 -E-XL-M1-C3 cylindrical roller bearing, with dimensions of 120 × 215 × 58 mm, offers high radial load-carrying capacity and axial guidance in one direction.

The NJ2224 -E-XL-M1-C3 cylindrical roller bearing is a single-row rolling bearing with a 120 mm bore, an outer diameter of 215 mm and a width of 58 mm. This FAG design primarily withstands very high radial loads and, thanks to the NJ design, provides axial guidance in one direction. The open design without an integrated seal allows the bearing to be integrated directly into an existing lubrication system. The factory-set increased clearance (C3) ensures reliable operation even under conditions of increased heat generation.

In which applications is the NJ2224 -E-XL-M1-C3 cylindrical roller bearing used as a support bearing?

This single-row cylindrical roller bearing is primarily used in mechanical bearing arrangements subject to high radial forces. As a support bearing, the NJ design absorbs not only the main load but also unilateral axial forces, whilst allowing axial displacement in the opposite direction. This facilitates the compensation of shaft thermal expansion. The solid brass cage also performs well under demanding operating conditions involving vibrations or fluctuating speeds.

What does the version with C3 clearance and a brass cage mean?

The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This increased clearance between the rollers and raceways effectively compensates for thermal expansion at operating temperatures ranging from –30 to +150 degrees, without causing the bearing to become stressed. The M1 brass cage guides the cylindrical rollers precisely and offers high strength compared to standard sheet metal cages. As the inner ring can be removed from one side, assembly onto the shaft and housing can be carried out separately.
