NKIB5914 NKE needle roller bearing

NKE NKIB5914 Combined Needle Roller Bearing (Double Direction)

The NKE NKIB5914 is a high-specialty rolling unit designed to simultaneously handle high radial loads and moderate axial loads acting in both directions. Its architecture consists of a radial needle roller assembly integrated with a double-direction ball bearing system. A defining feature of the NKIB series is the two-piece inner ring, which is clamped during installation to provide precise, rigid guidance for 70 mm shafts. It is the premier "locating bearing" choice for applications where space efficiency and running accuracy are paramount.

Application

• CNC Machine Tools: Bidirectional axial stabilization for drive shafts and auxiliary spindles.
• Automation & Robotics: Compact drives and joints for industrial robots where load-to-weight ratio is critical.
• Industrial Gearboxes: Support for gear shafts subjected to reversing longitudinal forces at high speeds.
• Pumps & Compressors: Securing rotor axial position while managing heavy radial loads.
• Packaging Machinery: Guiding control rollers in tight installation environments.

Technical Specification

• Manufacturer: NKE Bearings (Austria).
• Designation: NKIB5914.
• Dimensions: 70 mm (ID) × 100 mm (OD) × 34 mm (Total width).
• Type: Combined bearing (radial needle + double direction angular contact ball).

Features and Benefits

• Bidirectional Axial Locating: Eliminates the need for two separate thrust bearings, significantly shortening the overall shaft length.
• High Rigidity: The dense needle arrangement ensures excellent radial support with minimal deflection.
• Space Efficiency: The 100 mm outer diameter allows for the design of slender and lightweight machine housings.
• Simplified Installation: The split inner ring ensures a safer fitting process on the shaft, protecting the raceways.
• Austrian Quality: NKE production guarantees running accuracy and a long fatigue life.
