Cylindrical Roller Bearings FAG NJ2322 -E-XL-M1-C3

The FAG NJ2322 -E-XL-M1-C3 cylindrical roller bearing combines high radial load capacity (110 × 240 × 80 mm) with a support bearing function and a brass cage for demanding bearing applications.

The FAG NJ2322 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing designed for heavy-duty applications. Thanks to the line contact of the cylindrical rollers, this design can withstand considerable radial forces. With a bore of 110 mm, an outer diameter of 240 mm and a width of 80 mm, this design complies with tolerance class P0/PN or ABEC 1. The open bearing is designed for use with external lubrication.

What function does the NJ design fulfil within the system?

As an NJ design, the bearing serves as a support bearing in industrial shaft mountings. It guides the shaft in one axial direction whilst allowing axial displacement in the opposite direction. Thanks to the inner ring, which can be removed from one side, the bearing can be fitted separately during installation and maintenance. The open design is used in enclosed housings with an existing lubrication circuit.

What are the functions of the brass cage and the C3 bearing clearance?

The solid brass cage (M1) guides the rollers stably under vibrations and dynamic loads. The increased radial clearance (C3) helps to compensate for thermal expansion when temperature differences occur between the shaft and the housing during operation. For the permissible temperature range of -30 to +150 degrees, this design ensures dimensional stability. As the outer ring is manufactured without a groove or lubrication bore, the lubricant is supplied via the surrounding structure.
