The NSK FWF series needle cage is a component that keeps the needle rollers separated and guided in a bearing. 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. If you need a specific size, send us the part number on WhatsApp and we'll quote it for you.
The FWF series designation reads as a code that combines letters and numbers. The letters FWF identify the needle cage family. The numbers that follow indicate internal dimensions: for example, in FWF-202540W the digits are grouped in pairs and refer to diameter and width measurements. The final W suffix appears in all the examples and distinguishes a construction variant within the series. To select the correct cage, the most practical approach is to start from the complete part number shown on the bearing or on the drawing.
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 applications where radial space is critical, such as gearboxes, camshafts and guiding mechanisms. They are also used in the automotive sector and in agricultural machinery. MR Accesorios Industriales sells them for replacement and maintenance, and you can ask about the size you need.
To choose an FWF cage, take into account the shaft diameter, the outer diameter and the width of the assembly. The cage must be mounted with the correct orientation and with adequate lubrication to prevent premature wear. Alignment between shaft and housing is essential: excessive misalignment can generate lateral loads that shorten service life. If the original bearing has a specific suffix, it is best to keep it to ensure compatibility.
NSK needle cages can be interchanged with those of other brands that follow the same dimensional nomenclature, but there is no automatic equivalence between part numbers. If you have a cage from another brand or an unidentified part, send us the main measurements (inner diameter, outer diameter and width) and we'll tell you the compatible alternative. At MR Accesorios Industriales we work with leading brands and can quote the exact reference you need.
If you already have the part number of the FWF cage you are looking for, write to us on WhatsApp and we'll quote it for you shortly. We can also advise you if you need to assemble a complete needle roller bearing assembly. MR Accesorios Industriales has more than 80 years of experience in the field and helps you find the right component for your application.
