Detailed parameters

1. Product Overview & Parameter Comparison

NKXR series needle roller bearings (NKXR40Z, NKXR45Z, NKXR50Z) are engineered for high radial load capacity in compact spaces. Key parameters:

Model Inner Diameter (mm) Outer Diameter (mm) Width (mm) Dynamic Load Rating (kN) Max Speed (rpm)
NKXR40Z 40 50 30 28.5 6,000
NKXR45Z 45 58 35 34.2 5,500
NKXR50Z 50 62 35 39.8 5,000

Compared to standard models, NKXR series features 15% higher load capacity through optimized roller geometry[10].

2. Detailed Applications

Primary industrial uses include:

  • Automotive Transmissions: Space-saving solution for gear shift mechanisms
  • Packaging Machinery: High-speed rotary cam followers
  • Construction Equipment: Heavy-duty pivot points in excavator arms

Specialized variants available for extreme environments (-40°C to 200°C)[10].

3. Installation & Maintenance Guidelines

Critical installation steps:

  1. Clean housing surfaces (Ra ≤ 0.8 μm)
  2. Use hydraulic press with alignment tool (max 50 kN force)
  3. Apply EP2 grease to roller ends

Maintenance intervals: 2,000 operating hours or 6 months (whichever comes first)[1].

4. Industry-Specific Use Cases

4.1 Wind Turbine Pitch Systems

NKXR45Z bearings withstand 10⁷ load cycles in variable wind loads.

4.2 Robotics Joints

Precision NKXR40Z units enable ±0.01° repeatability in articulated arms.

5. Verified Customer Success Stories
