NF Series Cylindrical Roller Bearings
NF-type cylindrical roller bearings feature a double flange on the inner ring and a single flange on the outer ring. They can withstand radial loads and unidirectional axial loads, and are capable of restricting axial displacement of the shaft in one direction.
With a separable design that facilitates installation and removal, these bearings offer excellent rigidity and load-carrying capacity. They are suitable for transmission equipment such as gearboxes, machine tools, and electric motors that require unidirectional axial positioning and operate at high speeds.
