NTN K series needle cages are precision components that guide and retain needle rollers in bearings and transmission applications. They are used when radial space is limited and high load capacity is needed with a reduced diameter. MR Accesorios Industriales sells this line for industrial equipment in Buenos Aires, Argentina, and advises you to choose the right size for your application.

The K series designation is read with the bore diameter, outer diameter and width measurements, separated by the × sign. For example, K4×6×7.8XT2 indicates 4 mm bore diameter, 6 mm outer diameter and 7.8 mm width. The XT2 suffix identifies a cage variant with specific material or treatment characteristics. The K‥T2 series groups these cages under the same dimensional criteria and suffix. To correctly interpret each code, keep in mind that the numbers always correspond to those three dimensions in millimeters.

These cages are used in industries such as metalworking, food, mining and machine tool manufacturing. In Argentina, they are common in transmission equipment, pumps, compressors and roller systems where space is critical. Their design allows needle assemblies to be mounted directly on the shaft, which simplifies the design and reduces the overall bearing size. MR Accesorios Industriales supplies them for equipment maintenance and manufacturing in Buenos Aires, Argentina and the rest of the country.

To select the right cage, check the shaft and housing dimensions, and make sure the cage has the correct radial clearance. Mounting requires precise alignment and adequate lubrication to avoid premature wear. The cage must be firmly guided, without interference, and it is recommended to clean and lubricate the needles before installation. If the equipment operates at high speeds or with variable loads, consult with our technical team to choose the most suitable variant.
