Usage

For devices with a high center of gravity, swaying of the device can be reduced by installing anti-vibration products at a position near the center of gravity inside the device.

Characteristic Data

Selection Points

Read the resonant frequencies of the mounts depending on the load from the table on the left and select the mount where the resonant frequency is 1/2 (0.5 times) or less the frequency of the vibration you want to isolate.

Selection Examples
If you want to isolate the vibrations from a pump running at 1,800 rpm with a load of 50 N on each mount

■The vibration frequency generated by the pump is 1,800 rpm/60 seconds = 30 Hz.
　Therefore, select mounts that have a resonant frequency of 30 Hz/2 = 15 Hz or less.
■The BBL25D013 (resonant frequency of approx.
　13 Hz with a 50 N load) or BBL35D007 (resonant frequency of approx. 11 Hz with a 50 N load) are suitable for this case.

Usage Warnings

・If the resonant frequency of the mount is 1/√2 (0.7) times or higher than the vibration frequency you want to eliminate, damping effect will not act and the vibrations will be amplified.
　The mount should be used loaded under compression.
・It cannot be used with a tensile or shear load. (Refer to the examples above)
　You should also ensure that the mounts are not loaded with tensile or shear loads during transport and storage. The mount may become damaged if subjected to tensile or shear loads.
