NJ Series Cylindrical Roller Bearings

The NJ series cylindrical roller bearings feature a double-flanged outer ring and a single-flanged inner ring. They are capable of withstanding radial loads plus unidirectional axial loads, restricting axial displacement in one direction. These bearings offer high rigidity, strong load-carrying capacity, and a wide range of applicable speeds.

The separable design facilitates easy installation and removal. These bearings are suitable for transmission equipment requiring unidirectional axial positioning, such as electric motors, gearboxes, machine tools, and fans, offering stable operation and reliable precision.
