Key Features

  1. Ultra-lightweight Construction
    • Advanced wall-thinning technology reduces weight by 40-60% compared to conventional bearings
    • Materials: Vacuum-degassed bearing steel (SUJ2) or SiC ceramic for HRC60+ hardness and 10^7+ fatigue cycles
  2. ISO Metric Compliance
    • Full adherence to ISO 15:2011 dimensional standards with IT5-class tolerance control
    • 72/73/74 series compatible with global OEM replacement parts
  3. Modular Sealing Solutions
    • Available in open (-RS), double-lip (-2RS), and labyrinth (-Z) configurations
    • IP65-rated integrated shields for environments with ≤10mg/m³ dust concentration
Application
The bearings can be used in the following industries
  • Semiconductor: Wafer stages in lithography tools (radial runout ≤2μm)
  • Aerospace: Gyroscope supports in inertial navigation systems (-55℃~+125℃ operation)
  • Medical: PET-CT gantries (service life ≥20,000 hours)
