Product Overview: The NKIB 5906 Combined Needle Roller/Angular Contact Ball Bearing
The NKIB 5906 is a high-precision bearing designed to handle both radial and axial loads simultaneously. With dimensions of 30x47x25mm, this compact unit integrates a needle roller bearing to manage high radial forces and an angular contact ball bearing to accommodate axial loads in a single direction. This combination makes it an excellent space-saving solution for applications requiring high rotational accuracy and rigidity. Part of our specialized Combined Needle Roller Bearings range, the NKIB 5906 is engineered for demanding environments where both types of loads are present on a single shaft.
As a leading supplier of industrial components, we ensure our NKIB 5906 bearings meet stringent quality standards. This bearing is typically used in pairs with another combined bearing (like the NKIA 5906) to handle axial loads in both directions, providing complete and rigid shaft support.

Key Features of the NKIB 5906 Bearing
- Dual-Function Design: Combines a needle roller bearing for radial loads and an angular contact ball bearing for single-direction axial loads.
- High Radial Capacity: The needle roller component offers excellent support for heavy radial forces within a small cross-section.
- Uni-Directional Axial Support: The integrated angular contact section is precisely designed to handle thrust loads in one direction.
- Space-Saving Construction: Its compact, integrated design eliminates the need for two separate bearings, simplifying machinery design and assembly.
- High Rotational Accuracy: Engineered for precision, making it ideal for applications where minimal runout is critical.
- Includes Inner Ring: Provides a hardened and ground raceway, ready for installation on standard shafts.
Common Applications of NKIB 5906 Bearings
- Machine Tool Spindles: Provides the high rigidity and precision required for main spindles in lathes and milling machines.
- Industrial Gearboxes: Supports gear shafts that are subjected to both significant radial and axial forces.
- Printing Presses: Ensures precise alignment and smooth rotation of rollers and cylinders.
- Robotics: Used in robotic arms and joints where compact size and multi-load capability are essential.
- Pumps and Compressors: Ideal for supporting shafts in high-performance fluid machinery.
- Textile Machinery: Suitable for complex rotating assemblies that require robust and precise motion control.
Benefits of Using the NKIB 5906 Bearing
- Enhanced System Rigidity: The combined structure provides superior stiffness against both radial and axial deflection, improving machine accuracy.
- Simplified Assembly: Installing one combined unit is simpler and faster than mounting two separate bearings, reducing labor costs.
- Optimized Machine Design: The compact footprint allows for more streamlined and smaller machine designs without sacrificing performance.
- Improved Reliability: Reduces the number of components, leading to fewer potential points of failure and a more robust system.
- Cost-Effective Solution: Often more economical than purchasing and installing a separate radial and thrust bearing.
- Precise Shaft Location: Ensures accurate axial positioning of the shaft, which is critical for high-precision operations.
