NJ style single row – NJ style cylindrical roller bearings have two machined flanges in the outer ring plus a machined flange on one side in the inner ring. The roller and cage assembly is in the outer ring. The integral flange on the inner ring enables this bearing to handle an axial load.
Large-sized bearings are fitted with machined brass cages of normal design, i.e. cages of separable design guided on rolling elements M, on the outside surface MA or inner surface MB.In case of heavy loads and high speeds, cages are made in one piece.

FAQ1: What are the common models and dimensions of NJ series cylindrical roller bearings?
“NJ” design: The outer ring has two integral flanges, and the inner ring has one integral flange, allowing for unidirectional axial displacement.
Common models include NJ2316, NJ2317, and NJ2318 bearings;
The dimensions are: 80x170x58mm; 85x180x60mm; 90x190x64mm bearing.
These are high-load capacity NJ series bearings.
FAQ2: Differences between NJ and NU series cylindrical roller bearings:
NU series cylindrical roller bearings: The inner ring has no flange. It can move axially in both directions. It cannot withstand any axial load.
NJ series cylindrical roller bearings: The inner ring has one flange. It can fix the shaft in one direction and withstand unidirectional axial load.
