Needle roller bearings rely on a cage to keep the needles evenly spaced and properly guided. The NTN KV series is a needle cage built for that task, handling radial loads in places where radial room is tight. MR Industrial Accessories LLC supplies these cages to maintenance and purchasing teams across the United States and Latin America, and can help you confirm the exact reference before you order.
Reading a KV designation is straightforward once you know the layout. Take KV34×40×39.3X1ZWS: KV marks the needle cage family. The three main figures are metric—34 mm for the bore, 40 mm for the outside diameter, and 39.3 mm for the width. The trailing characters, such as ZWS, point to specific cage details like material or surface treatment. Always match those dimensions and the suffix to your application before selecting a part.
These cages appear in automotive assemblies, machine tools, power transmission units, and agricultural equipment. They are also common in gearboxes, pumps, compressors, and roller systems. Their low radial profile lets them fit into spaces where a conventional bearing would not go. MR can advise on cage selection based on your load and operating speed.
When choosing a KV needle cage, check bore diameter, outside diameter, width, and the suffix that covers sealing or lubrication. Use the right tools during assembly to avoid damaging the needles or the cage. Alignment and lubrication both matter for service life. If you need technical guidance, the MR team can assist with selection and installation.
NTN KV series cages can be interchanged with other manufacturers' cages that share the same dimensions and specifications. When comparing equivalents, look beyond dimensions to the suffix and cage features. If you have a part number from another brand, we can help you find the matching NTN reference. Interchangeability depends on keeping the original tolerances and design.
