NKIA5912 NKE needle roller bearing

NKE NKIA5912 Combined Needle Roller Bearing

The NKE NKIA5912 is a highly specialized combined bearing unit. This design integrates a radial needle roller bearing with a single-row angular contact ball bearing. It allows for the simultaneous accommodation of heavy radial loads within a minimal design envelope while locating the shaft in one axial direction. It is the perfect solution for applications where guiding precision must be paired with compact external dimensions (85 mm OD).

Application

• Industrial Gearboxes: Compact support for intermediate shafts subjected to axial thrust.
• Machine Tools: Precise guidance for spindles and high-dynamic drive shafts.
• Multi-piston Pumps: Handling loads resulting from operating pressure and shaft rotation.
• Automation: Robotic arms and positioning mechanisms requiring high rigidity.
• Automotive Engineering: Transmissions and drivetrains in specialized vehicles.

Technical Specification

• Manufacturer: NKE Bearings (Austria).
• Designation: NKIA5912.
• Dimensions: 60 mm (ID) × 85 mm (OD) × 34 mm (Width).
• Type: Needle roller / angular contact ball bearing (combined).
• Load Capability: Radial and axial (unidirectional).
• Material: High-purity, heat-treated bearing steel.

Features and Benefits

• Space Saving: Replaces two separate bearings, allowing for shorter shafts and smaller housing designs.
• High Rigidity: The needle roller assembly ensures minimal radial deflection under heavy pressure.
• Precise Guidance: The integrated ball section eliminates axial play in the fixed direction.
• Low Friction: NKE’s superior raceway finish reduces heat generation and operating noise.
• Austrian Quality: Manufacturing to rigorous standards ensures long fatigue life.

Why Choose This Product

By investing in the NKE NKIA5912 bearing, you are choosing a premium product that simplifies your machine design. By combining two functions into one housing, you reduce the risk of assembly errors and lower the overall weight of the drive system. It is a reliable solution for engineers seeking maximum performance in limited spaces, guaranteed by the reputable European brand NKE.
