The NTN KMJ series needle cage is a component that keeps the needles of a bearing separated and guided, allowing them to work uniformly and support radial loads. It is used in assemblies where radial space is limited and high load capacity is required. MR Accesorios Industriales sells this series with standardized dimensions and variants with suffixes that indicate particular characteristics. If you need a specific size, write to us via WhatsApp with the part number.

The KMJ series designation is read as a set of dimensions: for example, KMJ16×22×13S indicates a bore diameter of 16 mm, an outside diameter of 22 mm and a width of 13 mm. The final letter S indicates a variant with specific manufacturing characteristics. In cases such as KMJ20×26×13.8X1S, the suffix X1 may indicate a version with a dimensional or material modification. These codes allow you to quickly identify the size and configuration of the cage.

These cages are used in industries such as automotive, metalworking and agricultural machinery manufacturing, where needle roller bearings are common in transmission cases, pumps, compressors and linear motion equipment. In Argentina, they are found in applications ranging from power tools to industrial conveyors, whenever a compact solution for radial loads is required.

To select the appropriate cage, take into account the shaft diameter, the housing and the available width. Lubrication is key: ensure that the lubricant reaches the needles and that the cage does not obstruct the flow. Alignment between shaft and housing must be precise to avoid premature wear. If the environment has contaminants, consider additional protections. Mounting must be done with suitable tools to avoid damaging the cage or the needles.

NTN needle cages can be interchanged with those of other brands that follow the same standardized dimensions, such as SKF, FAG or NSK, as long as the dimensions and needle type match. It is important to verify the complete part number and tolerances. If you have an unidentified part, we can help you find the appropriate equivalent.
