Innovative X-Contact Geometry

  • Crossed four-point contact design (combined contact angles α=35°/55°) increases axial stiffness by 18% over conventional four-point bearings
  • Optimized stress distribution ensures maximum contact stress <1,800MPa under radial load P_r=8.5kN

Metric Precision Manufacturing

  • Full compliance with ISO 492:2018 metric standards (bore d=10-100mm, OD D=26-150mm)
  • Raceway roundness error ≤1.2μm, rotational accuracy meeting P4 class (GB/T 307.1)

Thin-wall Enhancement Technology

  • 0.8-1.5mm ultra-thin rings (wall thickness/diameter ratio <0.03) treated with vacuum quenching + ion nitriding
  • Dynamic stiffness K_r=1,200N/μm at rotational speed n=12,000rpm
Application
The bearings can be used in the following industries
  • Industrial Robotics: SCARA robot wrist joints (repeatability ±0.02mm)
  • Aerospace: Satellite solar panel drives (15-year service life / 5×10^5 cycles)
  • Precision Metrology: CMM rotary tables (runout ≤3μm)
  • Medical: Da Vinci surgical robot arms (10^6 fatigue cycles under alternating loads)
