The NTN KV series needle roller cage is a component that keeps the needles of a bearing aligned and separated, without inner or outer rings. It is used when radial space is limited and high load capacity is required. MR Accesorios Industriales sells this series in standard sizes for different applications. If you need a specific size, message us on WhatsApp with the part number and we will quote it.

The KV series designation is read as KV followed by the dimensions: bore diameter, outside diameter and width, separated by the × sign. For example, KV30×35×13S indicates 30 mm bore diameter, 35 mm outside diameter and 13 mm width. The final suffix S indicates a cage variant; in some cases an X with a number appears, as in KV7×10×12.8X3S, which identifies a particular configuration. These dimensions allow you to locate the exact reference in the catalog.

These cages are used in machine tools, pumps, compressors, electric motors and transmission equipment, where radial space is critical. In Argentine industry they appear in spindle maintenance, gearboxes and precision mechanisms. Because they have no rings, they allow a more compact design and lower weight. They are common in applications requiring high rigidity and moderate speed, and where the shaft and housing are already hardened and ground.

To select the correct cage, take into account the shaft diameter, housing diameter and available width. The cage must be mounted with precise alignment to avoid premature wear. Proper lubrication —oil or grease— is essential to dissipate heat and extend service life. Verify that the raceways have adequate hardness and roughness. Incorrect fit during assembly can generate noise and early failures.

NTN KV series needle roller cages can be interchanged with equivalent components from other brands that follow the same standard dimensions. If you have an unidentified part or the part number from another brand, we can help you find the equivalent. Interchangeability depends on tolerances and the specific suffix, so it is important to verify the complete designation. Consult us with your application data and we will advise you.
