A needle cage from the NSK FBN series holds and steers the needles within a bearing assembly. On its own it is not a finished bearing; it works together with the needles and the raceways to carry radial loads where space is tight. Typical uses include transmissions, pumps and general industrial machinery. MR Industrial Accessories LLC supplies this line to customers throughout the United States and in several Latin American countries.
Reading the code: FBN marks the NSK needle cage family. A complete reference such as FBN-323629WA combines figures that describe the size and a letter suffix that can signal a design or material variation. In that example, FBN-323629WA is an FBN cage with its own size and configuration. Matching a cage correctly starts with knowing the housing dimensions and which needles will run in it.
Where they are used: automotive, metallurgy, food processing and machine tool applications all rely on this type of cage. You will also find them in gearboxes, hydraulic pumps, compressors, electric motors and transmission equipment, as well as in agricultural and road machinery where precision and ruggedness matter. Because the design is compact, the bearing envelope can be reduced while radial load capacity is maintained.
Selection points: work from the shaft diameter, the housing outside diameter and the width, and confirm that the cage suits the needles and raceways in the assembly. Check alignment during installation and avoid impacts that could deform the cage. Use the lubricant specified for the assembly and keep the bearing seal in place to block contaminants. Handling the cage carefully at assembly supports a longer service life for the component and the machine.
Interchange: cages from other manufacturers can be used when their dimensions and specifications line up. Compare the main measurements plus the needle type and cage material before substituting. If you are unsure, send the original part number and we will identify a compatible option. Tolerances and the required load capacity have to be preserved for the swap to work.

Frequently asked questions
- What is an FBN needle cage?
- It is a precision part that retains and guides the needles inside a bearing. The NSK FBN series fits assemblies with limited radial space that still need high load capacity.
- How do I choose the right needle cage?
- Start with the shaft, housing and width dimensions, and confirm the needle type. With those details we can quote the FBN cage that matches your application.
- Can I replace an NSK cage with another brand?
- Yes, provided the dimensions and technical specifications are equivalent. Send us the original part number and we will suggest a compatible alternative that meets the requirements.
