N Series Cylindrical Roller Bearings

N-type cylindrical roller bearings feature a separable design with an inner ring that has no flanges and an outer ring with double flanges, allowing for free adjustment of axial displacement. They are primarily designed to withstand purely radial loads and cannot accommodate axial forces.

These bearings offer high rigidity, strong load-carrying capacity, and minimal radial clearance, ensuring stable rotational precision. They are suitable for applications involving high rotational speeds, heavy radial loads, and the need to compensate for thermal expansion and contraction of the shaft.

They are widely used in general machinery and heavy-duty transmission equipment such as electric motors, machine tool spindles, gearboxes, fans, and compressors. They are easy to install and remove, and offer stable and reliable operation.
