Vibration Reduction Products

OVD

Oil-type Viscosity Damper
Product Application
  • Ensures dynamic stability of equipment when installed with a pneumatic mount system
  • Reduces tack time for production inspection equipment that induces dynamic load
  • Equipment and sites requiring ultra-precision micro-vibration control, such as in semiconductor, LCD, and OLED industries
  • Various inspection equipment, laser-related devices, 3D measuring instruments, and other precision measurement equipment
Product Features
  • Suppresses displacement caused by shock vibrations when combined with a pneumatic mount
  • Ensures consistent damping performance with the same damping force during tension and compression
  • Minimal fluctuation in the natural frequency of the pneumatic mount due to damping force
  • Capable of controlling displacement on both vertical and horizontal axes at standard levels
  • Ensures damping force performance even at small displacements, addressing the drawback of conventional dampers
