The NTN KV series needle cage is a precision component that guides and retains needle rollers in bearing assemblies. It is used to build needle roller bearings without an inner ring, where radial space is limited and high load capacity is required. MR Accesorios Industriales sells this series for industrial applications in Buenos Aires, Argentina.
The KV series designation is read as KV followed by the dimensions: needle diameter, outer diameter and width, separated by the × sign. For example, KV43×48×37.8XZWS indicates a cage with 43 mm diameter needles, 48 mm outer diameter and 37.8 mm width. The XZWS suffix identifies design features specific to the series, such as the cage type and sealing. The K series, in turn, shares the same dimensional logic.
These cages are used in industries such as automotive, machine tools, transmission equipment and linear motion machinery. In Argentina, they are found in gearboxes, pumps, compressors and guidance systems. Their compact design allows them to be mounted in tight spaces, supporting high radial loads.
To select the correct cage, take into account the shaft diameter, load and operating speed. Installation requires precise alignment and adequate lubrication; the assembly sealing protects against contaminants. The cage must be properly centered and have the specified radial clearance to prevent premature wear.
NTN KV series needle cages can be interchanged with those from other manufacturers that follow the same dimensional nomenclature. Always verify tolerances and cage type before replacing. If you have another brand's part number, we can indicate the compatible equivalent.
