Vibration and Shock Control / Silicone Gel Stud Mounts

Feature:

      Soft Enough To Damp To Lower Frequencies Than Rubber Mounts.
      Broad Temperature Range.
      Extremely Strong Metal Bond.
      Ideal for Sensitive Equipment.

Ultra soft high damping silicone gel metal bonded mount.Outstanding vibration and shock absorbing properties. Able to damp to lower frequencies than traditional rubber or neoprene stud mounts. Can also absorb tiny vibrations. Suits load from 2kgs to 300kgs. Ideal for pump noise control, vibration protection of truck or bus mounted computers.

High strength metal to silicone bond mount. Male blank versions available for space saving requirements. Broad operating temp, stable performance over -40c to 200c. Excellent weatherability, Ozone UV and good chemical resistance.15 mount sizes available. As the mounts are very soft they can only be used in compressive direction only. Not suitable for shear unless shear load is buffered. Compress up to 33% for optimum performance. This silicone based gel offers excellent shock and vibration damping. The material disperses impact three dimensionally due to its unique molecular structure. Can be used with a locking nut to prevent shaking loose from vibration.

Material Properties



Terminology

Optimium Load
Each of our vibration dampening products is designed to work best for a certain weight range (optimium load). Select the best part number based on the load of the vibrating object. Optimium load assumes four points of support (one sheet for the A.V silicone mats).
Resonance Point (Hz)
Resonance point is the frequency at which the object reaches maximium vibration when it is externally vibrated on a vibration damping product. Resonance point is determined by the spring constant of the vibration damping products and the weight of the vibrating object.
Resonance Magnification (dB)
Resonance magnification is the ratio, at resonance point, of the vibration amplitude with the vibration damping product to the level without them. The vibrating object will vibrate at about twice the amplitude at 6dB, at about five times at 14dB, and at about ten times at 20dB, compared to when no vibration damping products are used.
Recommended Frequency (Hz)
For effective vibration damping, the frequency of the vibrating object needs to be at least 2 x the square root of the resonance point. Recommended frequency is defined as the range above the frequency. Select the best one based on the frequency of the vibrating object.


Plating Material

Theta Series: Iron with trivalent chromate plating
MN Series: As above
BG Series: Bolt material: brass, Spring material: SWPA with trivalent chromate plating
SF-30/50: Choice of two materials:
1) Iron with trivalent chromate plating
2) SUS304
