The NTN K series needle cage is a component that guides and retains the needles in needle roller bearings, without an inner or outer ring. It is used to assemble units where the shaft and the housing act as raceways. MR Accesorios Industriales sells it in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission components.

The K series designation is read as K + bore diameter × outer diameter × width, followed by the letter T where applicable. For example, K16×20×10T indicates 16 mm bore diameter, 20 mm outer diameter and 10 mm width. The K‥T2 variant may appear in the catalogue for specific configurations. These dimensions allow the cage to be identified without ambiguity and the right one to be selected for the shaft and housing.

These cages are used in applications where radial space is limited and high load capacity is required. In Argentina, they are found in machine tools, pumps, compressors, electric motors, transmission equipment and agricultural machinery. Also in conveyor rollers and lifting systems. Their design allows them to be mounted directly on hardened and ground shafts, with housings that meet the necessary hardness and roughness.

To select a K cage, check that the shaft and housing diameters match the cage dimensions. The shaft must have suitable surface hardness and controlled roughness; the housing, a similar condition. Lubrication must be sufficient to prevent premature wear. During assembly, ensure alignment and avoid impacts that deform the cage. If the unit has no seal of its own, consider adding radial shaft seals to protect the raceways.

NTN K series needle cages can be interchanged with those of other manufacturers that follow the same dimensional designation, such as SKF, FAG or NSK, as long as the dimensions and the cage type match. In general, interchangeability is based on bore diameter, outer diameter and width, plus the tolerances of the unit.
