The FBN series needle cage is a ringless component that separates and guides the needles within a needle roller bearing. It enables compact rolling assemblies where radial space is limited but high load capacity and rigidity are required. MR Industrial Accessories LLC supplies this NSK series to customers throughout the United States and Latin America, providing quotes by WhatsApp or email with the exact part number.
The FBN code is structured in blocks. Letters indicate the needle cage family, while the following digits specify mounting dimensions. For instance, FBN-121613-E and FBN-121616-E share the 1216 prefix, and FBN-141812-E and FBN-141818-E begin with 1418. The E suffix denotes a construction variant within the series. To select the correct cage, provide the full code from the drawing or the part itself.
These cages are found in transmissions, pumps, compressors, machine tools, and automation equipment. In maintenance, they appear in gearboxes, electric motors, and textile or food machinery. Because they lack inner and outer rings, they reduce assembly size and allow more needles in the same space. They are a typical choice when the shaft and housing are already hardened and ground and serve as raceways.
When choosing an FBN cage, consider the assembly diameter and width, needle count and diameter, and the required radial clearance. Lubrication must match operating speed and temperature. Precise alignment between shaft and housing prevents localized loads. During installation, check that the cage is centered and that needles rotate freely without lateral forces.
Needle cages interchange across manufacturers by code and dimensions, not by brand. If you have a cage from another maker or an unmarked part, contact us with the main measurements and application details. We will identify the compatible equivalent. MR Industrial Accessories LLC works with NSK and other brands to help keep your equipment running.
To request an FBN series needle cage, send the complete code to MR Industrial Accessories LLC via WhatsApp or email. We will reply promptly with a quote and guidance on the variant that suits your mounting. You can also inquire about other needle roller bearing series and related components.
