Vibration Reduction Products

SCD

‌Stiffness Control Device
Product Application
  • Ensures dynamic stability of equipment when installed with a pneumatic mount system
  • Reduces tack time for production inspection equipment that generates dynamic loads
  • Equipment and sites requiring ultra-precision micro-vibration control, such as in semiconductor and display industries
  • Equipment requiring displacement control due to dynamic loads during operation
Product Features
  • Device for dynamic stiffness reinforcement of structures vulnerable to vibrations
  • Quantitatively changes the load applied to the structure to alter its dynamic characteristics
  • Capable of dynamic reinforcement control in multiple axes, including vertical and horizontal directions
  • Optimizes reinforcement points through pressure tuning
