The NTN KMJ series needle cage holds and guides the needles within a needle roller bearing, creating a compact assembly with high load capacity. It fits applications where radial space is tight and rigidity matters, such as gearboxes, pumps and machine tools. MR Industrial Accessories supplies this series in standardized dimensions and with sealing alternatives.

Reading a KMJ part number is straightforward once you know the layout. The numbers give the bore, outside diameter and width of the cage in millimeters. Take KMJ10×14×11.3XS: bore 10 mm, outside diameter 14 mm, width 11.3 mm. The XS suffix marks a variant with a special treatment or configuration, and the KMJ‥S series collects those versions. Always confirm the full part number to ensure it matches your bearing.

These cages appear in automotive, metalworking and food processing operations. You will find them in transmissions, oil pumps, compressors and packaging equipment. Their design supports assemblies with minimal radial space and tight tolerances, making them suitable for mechanisms that demand precision and resistance to combined loads. They are used both for replacement and for building new machinery.

When choosing a cage, check the shaft diameter, the housing and the width you have available. Lubrication must suit the operating speed and temperature; a high-viscosity grease is often recommended. Cleanliness and precise alignment during assembly help prevent premature wear. If the original bearing has seals, the cage must work with that system. Our technical team can assist if anything is unclear.

NTN needle cages can be interchanged with other brands that follow the same standardized dimensions, such as SKF, FAG or NSK, provided the dimensions and needle type match. Materials or treatments may differ from one manufacturer to another. If you have a part number from another brand or an unidentified part, we will identify the compatible equivalent and quote it for you.

To request a quote, send the exact cage part number via WhatsApp or email, for example KMJ12×16×11.3XS, or the bearing dimensions. Our team will reply promptly with options and alternatives. You can also ask about other needle roller bearing series and components.
