Usage

Vibration transmissibility (representative data)

Note: At maximum load tolerance of both BKK50D130/BKK30D130.
Example of reading: If the vibration frequency is 40 Hz, when BKK50D130 is used, the vibration transmissibility is 0.1 times, and the vibrations can be reduced to 1/10.

Application Examples

Aim：Isolate vibrations from a compressor unit
Method：Install 4 bolt-lock vibration isolation mounts between the compressor and the base.
Result：The vibrations transmitted from the compressor unit to the base were successfully reduced.
(The following graph shows the vibration acceleration in the vertical direction as measured at the top of the base)

Precautions for Use

・ If the vibration frequency is √2 times the natural frequency of the mount or less, the vibrations will be amplifi ed.
・ Fit the vibration isolation washer in the position where there is no gap. If screwed in, the mount is tightened hardly reducing the attenuation performance.
・ Although a stop nut is included, affi x using a double nut in cases where the mounts may move due to vibrations.
