BUILT-IN VIBRATION ISOLATION MOUNT (Heavy Weight Type)

E-9942

Material: Plate: FC200

Surface treatment: PAINTING

Feature: ■Built-in vibration isolation mount with polyurethane material which has high isolation performance.
■Vibration isolation from lower frequency.
Uses polyurethane foam material that can reduce vibrations even low frequency vibrations.
■Support for wide loading range
Wide available loading from 400N to 14700 N
■Various vibration isolation material
Can select 2-5 types of isolation material every fitting size. No need to change fitting size, even if loading is different.
■Built-in stopper mechanism for handling large vibrations such as earthquakes.

【Applications】
■Remove vibrations from the outside
■Reduce vibrations transmitted to the outside

※1 The resonant frequency is the calculated value when the maximum allowable load is applied.
※2 Applicable vibration frequency is vibration frequency which can be isolated. The estimated frequency is calculated such that the vibration in vertical direction can be decreased to 1/2 when maximum loading is applied.
※3 The vibration isolation material deformation is the calculated value when the maximum allowable load is applied.

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 motor running at 2,400 rpm with a load of 500 N on each mount

■The vibration frequency generated by the motor is 2,400 rpm/60 seconds = 40Hz.
　Therefore, select mounts that have a resonant frequency of 40 Hz/2 = 20 Hz or less.
■The BBH140D070 (resonant frequency of approx. 12 Hz with a 500 N load) or BBH100D013 (resonant frequency of approx. 13 Hz with a 500 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.
