The NTN K series needle cage is a component that guides and retains the needles in needle roller bearings, allowing a compact design with high load capacity. It is used in applications where radial space is limited and precise movement is required. MR Accesorios Industriales sells this series for the Argentine market.

The designation of the K series is read from the dimensions: for example, 8E-K10×14×16.8X1 indicates a bore diameter of 10 mm, outside diameter of 14 mm and width of 16.8 mm, with an X1 suffix identifying a cage variant. Similarly, 8E-K38×43×17 corresponds to 38 mm bore, 43 mm outside diameter and 17 mm width. The 8E prefix and the X1 or X2 suffixes distinguish construction or material features. These dimensions allow selecting the appropriate cage for each application.

K series needle cages are used in industries such as automotive, machine tools, transmission equipment, pumps and compressors. In Argentina, they are common in the repair of gearboxes, electric motors and roller systems. Their design allows compact radial mountings and supports high loads in reduced spaces, making them ideal for applications where conventional bearings do not fit.

To select a needle cage, take into account the housing and shaft dimensions, the required internal clearance and the type of lubrication. It is essential to verify alignment and cleanliness during mounting to avoid premature wear. The cage must be correctly guided and the needles must rotate freely. Adequate lubrication, whether grease or oil, extends the component's service life and reduces friction.

NTN K series needle cages can be interchanged with those from other manufacturers that follow the same dimensional nomenclature, such as SKF, FAG or NSK, provided the dimensions and cage type match. It is important to verify tolerances and material, since small differences can affect performance.
