NKIB5906 NKE needle roller bearing

NKE NKIB5906 Combined Needle Roller Bearing (Bi-directional)

The NKE NKIB5906 is a sophisticated hybrid rolling unit that integrates a radial needle roller bearing with a bi-directional angular contact ball bearing. Unlike standard combined bearings, this model allows for axial shaft location in both directions. By integrating two functions into a single 47 mm outer diameter housing, the NKIB5906 drastically reduces space requirements while offering the superior rigidity and radial load capacity of a needle bearing.

Application

• Gearboxes & Transmissions: Precise shaft support where alternating axial forces are present.
• Pumps & Compressors: Handling combined loads at high rotational speeds.
• Industrial Automation: Robotic joints and positioning mechanisms requiring bi-directional stabilization.
• Machine Spindles: Guiding high-dynamic drive shafts with varying pressure directions.
• Auxiliary Drives: Compact bearing arrangements in vehicles and agricultural machinery.

Technical Specification

• Manufacturer: NKE Bearings (Austria).
• Designation: NKIB5906.
• Dimensions: 30 mm (ID) × 47 mm (OD) × 30 mm (Total Width).
• Type: Combined needle roller / angular contact ball bearing (bi-directional).
