Cylindrical Roller Bearings FAG NJ2320 -E-XL-M1-C3

FAG NJ2320 -E-XL-M1-C3 cylindrical roller bearing: Single-row support bearing with brass cage, C3 clearance and main dimensions of 100 x 215 x 73 mm.

The FAG NJ2320 -E-XL-M1-C3 cylindrical roller bearing, as a radial rolling bearing, withstands high radial loads. Thanks to the line contact between the rollers and the raceway, this design offers high radial rigidity. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the bearing to support the shaft in one axial direction, whilst axial displacement in the opposite direction remains possible. The inner ring can be removed from one side, which facilitates the separate assembly of both bearing rings.

In which bearing arrangements is the NJ2320 -E-XL-M1-C3 cylindrical roller bearing used?

This single-row cylindrical roller bearing is designed for bearing arrangements subject to high radial loads. In the design, the NJ type is specifically intended as a support bearing to guide shafts radially and accommodate unilateral axial forces. As the outer ring has no groove or lubrication bore, the lubricant is supplied from the side via the housing cavity. Thanks to its open design, the component is suitable for enclosed housings with a lubricating oil or grease supply provided by the customer.

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

The brass cage guides the cylindrical rollers and is resistant to vibrations and high acceleration forces. In combination with the slightly increased radial bearing clearance (C3), this design helps to ensure that rotational freedom is maintained even when operational heating or tight fits reduce the internal bearing clearance. A permissible temperature range of -30 to +150 degrees is specified for use. The bearing is manufactured to tolerance class P0/PN or ABEC 1.
