The NTN K series needle roller cage is a component that keeps the needles of a bearing separated and guided, without inner or outer rings. It is used to assemble units where radial space is limited and high load capacity is needed. MR Accesorios Industriales sells this series in standardized dimensions, and we quote it for you on WhatsApp with the exact part number.

The K series designation is read as a set of dimensions: for example, K20×24×13SV4 indicates a bore diameter of 20 mm, an outside diameter of 24 mm and a width of 13 mm. The SV suffix identifies a steel cage with surface treatment, and the final number distinguishes design or tolerance variants. In K25×30×20SV3, the logic is the same: 25 mm bore, 30 mm outside diameter and 20 mm width. These dimensions are what define interchangeability with the housing and the shaft.

These cages are used in machine tools, pumps, compressors, electric motors, transmission equipment and agricultural machinery. In Argentina, the metalworking, food and equipment maintenance industries use them to replace worn assemblies or to manufacture special bearings. They also appear in gearboxes and linear guide systems where space is critical.

To select a K cage, take into account the hardness and finish of the raceways where the needles will roll, because the cage does not include rings. Radial clearance and alignment between shaft and housing are decisive to avoid point loads. Lubrication must be adequate and clean; in contaminated environments, it is advisable to evaluate external seals. Mounting is done with tools that do not deform the cage, and the SV series already incorporates surface protection that helps in demanding conditions.

Needle roller cages are available under different designations depending on the manufacturer, but standardized dimensions make it possible to find equivalents. If you have the part number of another brand or an unidentified part, send us the dimensions or the part number and we will indicate the compatible alternative. Interchangeability depends on keeping the same bore, outside diameter and width dimensions, and on respecting the cage type and treatment.

If you need an NTN K series needle roller cage, send the part number by WhatsApp to MR Accesorios Industriales. We will quote it promptly and advise you so that the part is the right one for your application.
