NKIA5908 NKE needle roller bearing

NKE NKIA5908 Combined Needle Roller Bearing

The NKE NKIA5908 is a sophisticated combined rolling bearing unit that integrates the functions of two different bearings into a single, compact envelope. This design consists of a radial needle roller assembly and a single-row angular contact ball bearing. This combination allows for the simultaneous accommodation of very high radial loads and axial forces acting in one direction. It is an ideal solution for applications requiring high stiffness and precision within drastically limited installation space (outer diameter is only 62 mm).

Application

• Industrial Gearboxes: Bearing support for intermediate shafts subjected to axial thrust from helical gearing.
• Machine Tools & Spindles: Precise guidance of high-dynamic rotating elements.
• Pumps & Compressors: Managing combined loads while maintaining compact equipment dimensions.
• Automation: Joints and pivot axes in manipulators requiring high transverse rigidity.
• Automotive Engineering: Transmissions and auxiliary drives in specialized vehicles.

Technical Specification

• Manufacturer: NKE Bearings (Austria).
• Designation: NKIA5908.
• Dimensions: 40 mm (ID) × 62 mm (OD) × 30 mm (Total Width).
• Type: Combined needle roller / angular contact ball bearing.
• Load Capability: High radial and unidirectional axial loads.
• Material: Premium heat-treated bearing steel.

Features and Benefits

• Unit Miniaturization: Replaces two separate bearings, enabling shorter shafts and reduced overall weight.
• High Radial Stiffness: Closely spaced needle rollers ensure minimal deflection under heavy pressure.
• Precise Shaft Locating: The ball section eliminates axial play in one direction, enhancing operational stability.
• Open Design: Facilitates free lubricant flow, improving heat dissipation and motion smoothness.
• European Quality: NKE production in Austria guarantees maximum fatigue life and 24/7 reliability.
