The NSK FWF series needle cage is a precision component that retains and guides the needles of a bearing, allowing them to work aligned and separated from each other. It is used in assemblies where radial space is limited and high load capacity is required. MR Accesorios Industriales sells this series for industrial applications in Buenos Aires, Argentina, and quotes it on WhatsApp with the exact part number.
The FWF series designation is read as a code that identifies the cage type and its main dimensions. In the example FWF-515650WZ, the letters FWF correspond to the needle cage family; the numbers that follow indicate key cage measurements, and the WZ suffix indicates a construction variant. To choose the correct reference, send us the full part number shown on your drawing or on the original part.
These cages are used in needle roller bearings that operate in transmissions, pumps, compressors, machine tools and automation equipment. In Argentine industry they appear in gear reducers, electric motors, mining equipment and agricultural applications, where space is limited and radial loads are high. MR Accesorios Industriales sells them for replacement and for the manufacture of assemblies.
To select an FWF cage, take into account the shaft diameter, the outside diameter and the width of the assembly, as well as the lubrication type and the bearing seal. The cage must be assembled with the needles correctly aligned and without forcing, checking that the radial clearance is adequate. Clean lubrication and precise alignment extend the service life of the component.
Needle cages are identified by codes that vary between manufacturers, but standardized dimensions make it possible to find equivalents. If you have the part number of another brand, write to us and we will tell you the corresponding NSK reference. At MR Accesorios Industriales we advise you so that the part is interchangeable without losing performance.
