Cylindrical Roller Bearings FAG NJ2312 -E-XL-M1-C3

The FAG NJ2312 -E-XL-M1-C3 cylindrical roller bearing, measuring 60x130x46 mm and featuring a solid brass cage, can withstand high radial forces as well as unilateral axial loads.

The NJ2312 -E-XL-M1-C3 cylindrical roller bearing is a single-row roller bearing from FAG in an industrial design. With a bore of 60 mm, an outer diameter of 130 mm and a width of 46 mm, this open bearing withstands heavy radial forces. Thanks to its NJ design, it serves as a support bearing: the inner ring has a fixed flange and can be removed from one side. This facilitates assembly and allows axial displacement in one direction.

What loads can the NJ2312 -E-XL-M1-C3 cylindrical roller bearing withstand?

Designs involving high continuous radial loads and single-sided axial guidance of the shaft relative to the housing constitute the primary area of application for the NJ design. The solid brass cage (M1) guides the roller elements precisely, even under severe vibrations. As the outer ring has no groove or lubrication bore, the lubricant is supplied via the surrounding housing structure.

What do C3 radial clearance and a brass cage mean in operation?

The designation C3 indicates a slightly increased radial bearing clearance. This additional radial clearance compensates for thermal expansion when temperature differences arise between the shaft and the housing. The bearing is designed for operating temperatures ranging from -30 to +150 degrees. Together with tolerance class P0 (ABEC 1), this design ensures smooth running. As an open design, the bearing requires external sealing of the bearing housing to retain the lubricant within the system and prevent the ingress of contaminants.
