The NTN K series needle roller cage is a bearing component that guides and retains the needles, without an inner or outer ring. It is used in assemblies where radial space is limited and high load capacity is needed. MR Accesorios Industriales sells this series with the backing of more than 80 years in the Argentine industrial market.
The K series designation is read as K followed by the dimensions: bore diameter, outside diameter and width, separated by the × sign. For example, K16×22×15.8X indicates 16 mm bore diameter, 22 mm outside diameter and 15.8 mm width. The X suffix indicates an execution with dimensions modified according to standard. These components are mounted directly on the shaft and housing, which act as raceways.
These cages are used in transmissions, pumps, compressors, machine tools and mining equipment, among others. In Argentina, they are common in the automotive, metalworking and food industries. Their compact design allows reducing the size of the assembly and supporting high radial loads at high speeds.
To select the right cage, take into account the shaft and housing diameters, the available width and the load to be supported. It is essential to verify the hardness and roughness of the raceways, since the shaft and housing must act as raceways. Lubrication must be adequate and alignment precise to avoid premature wear. Sealing the assembly protects against contaminants.
NTN K series needle roller cages can be interchanged with those of other brands that follow the same dimensional designation. If you have the code from another brand, we can indicate the equivalence. Always verify the tolerances and the X suffix to ensure compatibility. MR Accesorios Industriales advises you to find the right cage.
If you need a needle roller cage for your application, write to us on WhatsApp with the code or measurements. At MR Accesorios Industriales we will quote it shortly and give you the technical support you need.
