VIBRATION ISOLATION MOUNTS (Heavy Weight Type)

E-9923

Material
Case: SPHC
Rubber plate: NBR
Spring: Piano wire
Surface treatment
Trivalent chromate plating
Feature
Low natural frequency
■The spring structure allows the natural frequency in the horizontal direction to be lower.
High damping
■The material with a high damping property is used.
No need for power source
■Due to the configuration by spring and damping material, there is no need for power sources such as air and electricity.
Maintenance-free
■Since the loading is applied to the spring, the creep deformation of spring is less.

[Application]
Vibration isolation for electron microscope
-Scanning or Transmission Electron Microscope
Vibration isolation for semiconductor or inspection equipment
-Stepper, FIB equipment
Vibration isolation for chemical analysis equipment
-Micro hardness tester and magnetic resonance device
Various precision inspection and measuring instruments
