Selection Guide

From the table on the right, read the natural frequency for the mounted load and select the mount with the frequency of1/2 (0.5 times) or lower than the vibration frequency you want to isolate or remove.
(Refer also to the selection examples in the built-in vibration isolation mount page)

Characteristic data

Precautions for Use

・ If the natural frequency of the mount is 1/√2 (0.7 times) or more vibration frequency you want to remove, the vibration removal eff ect cannot be obtained and the vibrations will be amplifi ed.
・ In particular, when installed on equipment where the vibration frequency (rotation speed) changes such as motors and compressors, be careful because the mounted object may sway heavily if the vibration frequency becomes close to the natural frequency of the mount.
