NKIB5913 NKE needle roller bearing

NKE NKIB5913 Combined Needle Roller Bearing (Double Direction)

The NKE NKIB5913 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 angular contact ball bearing. A defining feature of the NKIB series is the two-piece inner ring, which is clamped during installation to provide axial stability for 65 mm shafts. It is the premier choice for locating bearing arrangements where space efficiency and running accuracy are paramount.

Application

• CNC Machine Tools: Precision support for auxiliary shafts and spindles requiring bidirectional stabilization.
• Industrial Gearboxes: Compact support for gear shafts subjected to reversing longitudinal forces.
• Pumps & Compressors: Securing the axial rotor position while managing heavy radial loads.
• Automotive Engineering: Transmissions and differential units in specialized vehicles.
• Packaging & Textile Machinery: Guiding control rollers in tight installation environments.

Technical Specification

• Manufacturer: NKE Bearings (Austria).
• Designation: NKIB5913.
• Dimensions: 65 mm (ID) × 90 mm (OD) × 34 mm (Total width).

Features and Benefits

• Bidirectional Axial Locating: Eliminates the need for two separate thrust bearings, shortening the shaft length.
• High Radial Capacity: The dense needle arrangement ensures rigidity and resistance to perpendicular forces.
• 59 Series Precision: An optimized cross-section allows for handling significant forces while maintaining low component weight.
• Simplified Installation: The split inner ring ensures a more predictable fitting process, protecting the raceways.
• Austrian Reliability: NKE production guarantees compliance with the highest European quality standards.

Why Choose This Product

By choosing the NKE NKIB5913, you are investing in a component that drastically simplifies bearing arrangement design. In 65 mm shaft applications where bidirectional axial stabilization is required but housing space is limited, the NKIB series is unrivaled. It combines Austrian precision with innovative geometry, leading to fewer failures and a longer service life for your machinery.
