Cylindrical Roller Bearings FAG NJ2238 -E-XL-M1-C3

The FAG NJ2238 -E-XL-M1-C3 cylindrical roller bearing, with a 190 mm bore and a brass cage, offers a robust solution for radial loads.

This single-row cylindrical roller bearing, model NJ2238 -E-XL-M1-C3 from FAG, is designed to accommodate high radial forces. Thanks to its dimensions – an inner diameter of 190 mm, an outer diameter of 340 mm and a width of 92 mm – the bearing can accommodate substantial radial loads. The open design without a seal is suitable for oil- or grease-lubricated bearing arrangements. The brass cage keeps the rolling elements in order during operation, whilst the design, in accordance with tolerance class P0/PN or ABEC 1, supports standardised mounting conditions.

What is the NJ2238 -E-XL-M1-C3 cylindrical roller bearing suitable for as a support bearing?

As a support bearing of the NJ design, the roller bearing absorbs radial forces and axial guidance forces from one direction. The inner ring is removable from one side, which facilitates the separate assembly of the inner and outer rings. This design also allows for axial displacement in the opposite direction. It is primarily used where thermal length changes in the shaft must be compensated for by the design.

What characteristics do the brass cage and C3 bearing clearance offer in the NJ2238?

The version with the C3 suffix has increased radial clearance compared with the standard version. This clearance compensates for operational temperature differences between the inner and outer rings, as well as press fits, to prevent the rollers from seizing. The brass cage provides strength against vibrations and impact loads. With a temperature range of -30 to +150 degrees, the bearing is designed for a wide range of operating conditions.
