The WJ series needle roller cage is a precision component that holds and guides the needle rollers in bearings. It is made of formed steel and is used to assemble units where radial space is limited. Its function is to ensure uniform separation of the needles, reduce friction and facilitate mounting in transmission and linear motion applications. MR Accesorios Industriales sells this series for the Argentine industrial market.

The WJ series designation is interpreted by its numbers: the first two indicate the bore diameter and the following ones the outer diameter and width, in millimeters. For example, WJ-101410 corresponds to a cage for a bore diameter of 10 mm, outer diameter of 14 mm and width of 10 mm. Likewise, WJ-162112 has 16 mm bore, 21 mm outer diameter and 12 mm width. These codes allow you to quickly identify the size without needing a catalog.

These cages are used in industries such as automotive, machine tools, packaging equipment, power transmission and agricultural machinery. In Argentina, they are common in gearbox repair, pumps, compressors and roller systems. Their compact design makes them suitable for reduced spaces where high load capacity and rigidity are required. MR Accesorios Industriales supplies them to workshops and plants that need to keep equipment running.

To select the correct cage, take into account the shaft diameter, the housing and the available width. The cage must fit without excessive clearance and allow free rotation of the needles. During mounting, check alignment and avoid blows that deform the lips. Proper lubrication is key: use oil or grease compatible with the material and operating conditions. If the cage is damaged, replace it together with the needles to ensure reliable operation.

NSK needle roller cages can be interchanged with those from other brands that follow the same dimensional designation, such as SKF, FAG or NTN, as long as the dimensions and needle type match. It is essential to verify the tolerances and the cage material before replacing. If you have doubts, ask us with the original part code and we will indicate the compatible equivalent. Not all series are interchangeable, so it is important to confirm the application.
