Material Specifications: Vacuum-degassed bearing steel with hardness of HRC 60-64 (oxygen content ≤ 8ppm), providing 20% longer service life than traditional bearings.
Precision Classes Available: P0 (general grade) and P6 (precision grade). For P6 class, raceway roundness error ≤ 1.5 μm with 30% reduced vibration value.
Core Technologies and Manufacturing Processes
Material Innovation
Using vacuum-degassed bearing steel (52100 chromium steel). The microstructure is optimized through quenching + tempering processes, with wear resistance 18% higher than that of ordinary electroslag steel. Suitable for harsh environments including high temperatures (-30°C to 110°C) and high dust levels.
Precision Design
  • Split structure: Inner and outer rings can be installed separately, supporting preload adjustment for high-precision transmission systems
  • Stamped steel cage: Optimizes roller guidance path, reducing friction loss by 15% and improving stability during high-speed operation
Construction Machinery Applications
  • Excavator travel mechanism: Widely used in excavators, bearing axial loads of 43 kN with failure rate less than 0.8%
  • Mining machinery: Replaces FAG bearings in gold mine crushers, reducing costs by 30% while increasing wear resistance by 18%
