NKXR30 NKE needle roller bearing

NKE NKXR30 Combined Needle Roller Bearing

The NKE NKXR30 is a highly specialized rolling component that combines the characteristics of a needle roller bearing (radial) and a cylindrical roller thrust bearing (axial). This hybrid design enables the simultaneous accommodation of heavy radial loads and significant axial loads acting in a single direction. By integrating two functions into one part, the NKXR30 allows for a drastic reduction in the bearing unit's dimensions, which is essential for modern, compact machinery.

Application

• CNC Machine Tools: Precise support for drive shafts and ball screws.
• Industrial Gearboxes: Managing shafts under combined loads within limited space.
• High-Pressure Pumps: Resilience against pulsating axial and radial pressures.
• Automation & Robotics: Stabilization of robotic arms and rotary mechanisms.
• Printing Machinery: Precise guidance of printing cylinders.

Technical Specification

• Manufacturer: NKE Bearings (Austria).
• Designation: NKXR30.
• Dimensions: 30 mm (ID) × 42 mm (OD) × 30 mm (Total Width).
• Type: Needle roller bearing with a cylindrical roller thrust assembly.
• Load Capability: High radial and unidirectional axial loads.
• Material: Premium heat-treated bearing steel.

Features and Benefits

• Integrated Design: Eliminates the need for two separate bearings, simplifying machine assembly.
• Extreme Load Capacity: Axial rollers offer significantly higher axial stiffness compared to ball versions (NKIA series).
• Operational Stability: The steel cage precisely guides the rolling elements, minimizing friction and heat.
• Compactness: Only 42 mm outer diameter with a high torque-carrying capacity.
• Austrian Precision: NKE products guarantee long service life even under 24/7 intensive operation.

Why Choose This Product

By choosing the NKE NKXR30, you are investing in European quality that translates into true operational reliability. This bearing is the perfect fit for applications where standard needle bearings fail under axial stress. With the NKXR30, your drive system will gain rigidity, directly improving machining accuracy and the longevity of other machine components.
