Needle cages in the NTN K ST series keep needles properly spaced and aligned inside a bearing assembly. They suit arrangements where radial room is tight but load capacity still matters. MR Industrial Accessories LLC supplies this series and helps you match the right size to your application.
Reading the code tells you the size. Take K16×20×17ST: bore 16 mm, outside diameter 20 mm, width 17 mm. The ST suffix denotes the cage and sealing variant. Related families such as K‥T2 and K‥S follow the same dimensional logic, though material or surface treatment may differ. Match the shaft and housing dimensions before ordering.
These cages appear across many industrial settings in the United States, Canada, Mexico and South America: machine tools, transmission equipment, pumps, compressors and conveying systems. Automotive plants, metallurgical operations and agricultural machinery builders also use them where space is limited and the assembly must stay compact.
Selection depends on dimensional fit with the shaft and housing, the lubrication method and the operating conditions. During installation, keep the work area clean, align components precisely and apply the specified lubricant to avoid early wear. For high-load or high-speed arrangements, review the technical recommendations for that duty.
NTN needle cages can interchange with other brands when dimensions and construction type align. Compare tolerances and materials to confirm compatibility. If you are unsure, our team can review your application and suggest an equivalent.
