The NSK FBN series needle cage holds and spaces the needles within a needle roller bearing, maintaining separation between the rolling elements so they do not touch each other. It suits assemblies with limited radial room that still require high load capacity in a slim profile. MR Industrial Accessories supplies it for needle roller bearing maintenance and replacement.

The FBN series code breaks down into a prefix and a suffix. FBN marks the needle cage family, the following digits describe the assembly dimensions, and the trailing letter Z denotes a construction variant. Part numbers such as FBN-354032Z and FBN-485323Z follow that layout: FBN block, numeric group, Z suffix. For a quote, provide the full part number as it appears on the bearing or drawing.

Typical applications include needle roller bearings in machine tools, gearboxes, pumps, compressors, transmission equipment and linear guide mechanisms. In maintenance work they show up in textile, food, automotive and packaging machinery, where radial space is tight and a rigid, low-weight solution is needed. They also serve in repairs of assembled bearings when the cage is renewed and the needles are reused.

When selecting an FBN cage, consider the number and diameter of needles it accommodates, the assembly width and the lubrication type of the equipment. Installation calls for cleanliness, aligned raceways and controlled radial clearance; a cage that is not seated properly or needles that are misaligned will wear faster. Use the lubricant specified for the operating temperature and speed, and check the housing seal to keep contamination out.

Needle cages from different manufacturers can be interchanged if the assembly dimensions, needle count and retention style match. A similar part number is not sufficient: compare bore diameter, outer diameter, width and the load capacity of the complete bearing. If you have the original part or another brand's part number, we can identify the compatible alternative and quote it.

To request an NSK FBN series needle cage, send the part number by WhatsApp to MR Industrial Accessories, along with a photo or the assembly measurements. We quote the exact part number or size you need and reply promptly.
