The NSK FBN series needle cage is a precision component that keeps the needle rollers separated and guided inside a bearing. Its function is to ensure uniform spacing between needles, prevent contact between them and allow them to rotate freely on the raceway. It is used in assemblies where radial space is limited and high load capacity is required, and it is obtained by exact code or size through MR Accesorios Industriales.

The designation of the FBN series is read from its alphanumeric code: the letters identify the family of needle cages and the numbers that follow indicate the mounting dimensions, such as bore diameter, outer diameter and width of the assembly. The WW suffix indicates a construction variant within the same series. A specific example is FBN-242825WW, where the numerical sequence orders the main dimensions of the cage. To correctly interpret each code, it is advisable to take the complete designation as it appears on the drawing or on the original part.

These cages are used in applications where radial space is critical: gearboxes, pumps, compressors, machine tools, transmission equipment and lifting mechanisms. In the Argentine market they appear in agricultural machinery maintenance, road equipment, production lines and industrial assemblies that require needle roller bearings with low weight and high rigidity. They are also used in assemblies where the raceway is ground directly on the shaft or on the housing, which simplifies the design and reduces the overall size of the bearing.

To select a needle cage, the exact match between the code and the mounting dimensions of the assembly must be verified. It is essential to check the shaft and housing diameter, the effective width, the number and diameter of the needles, and the type of sealing or oil seal that accompanies the bearing. During mounting, the cage must be centered without forcing, with adequate lubrication and correct alignment between shaft and housing. Poor seating or insufficient lubrication accelerate wear and affect the service life of the component.

Needle cages are sold by manufacturer code and can be interchanged between brands when the standardized dimensions and construction type match. It is not enough for the code to be similar: bore diameter, outer diameter, width, number of needles and raceway radius must be compared. If the customer brings a part without identification or the code from another brand, at MR Accesorios Industriales we quote it and tell you the compatible equivalent. The NSK FBN series is a common reference in this type of component.

If you need an FBN series needle cage, send the complete code or the mounting dimensions via WhatsApp to MR Accesorios Industriales. We quote the exact code or size you request and reply promptly. You can also ask us about other cage series, needle roller bearings and associated components: with the code or model you need, we move forward with the quote.
