Cylindrical Roller Bearings FAG NJ308 -E-XL-M1-C3

The FAG NJ308 -E-XL-M1-C3 cylindrical roller bearing, measuring 40x90x23 mm, offers high radial load-carrying capacity and acts as a support bearing with an axial guidance function.

The FAG NJ308 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing for industrial applications. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This design enables the bearing to accommodate not only radial forces but also unilateral axial forces. The solid brass cage guides the cylindrical rollers stably under mechanical loads. With dimensions of a 40 mm bore, 90 mm outer diameter and 23 mm width, this open bearing is designed for external lubrication systems.

What is the NJ308 -E-XL-M1-C3 cylindrical roller bearing suitable for?

Design engineers primarily use this design where high radial loads are present and shafts need to be supported in the axial direction. Typical applications can be found in industrial bearing arrangements and in general mechanical engineering. The inner ring, which can be removed from one side, allows the assembly to be fitted separately, which facilitates maintenance during operation. Thanks to its permissible temperature range of –30 to +150 degrees, the bearing is also designed for thermally demanding environments.

What advantages do the brass cage and C3 clearance offer with this bearing?

The combination of the M1 brass cage and the increased radial clearance (C3) offers functional benefits during operation. A brass cage is characterised by its dimensional stability under impact loads, vibrations and acceleration forces. The C3 clearance class provides additional clearance between the rolling elements and raceways. This compensates for operational heating or tight fits and helps to prevent mechanical stress. The component complies with tolerance class P0/PN or ABEC 1 and has an outer ring without a lubrication groove.
