MS91418 Series

MS91418 Series Vibration Isolators are Defined by the MS Specification as:  Mounts, Vibration, Cup-type, Classes A & B, Coarse Thread For Use With Electronic Equipment In Aircraft.

Low-frequency, highly damped mounts for a high level of vibration isolation. Hutchinson MS91418 Series mounts increase equipment reliability and extend component-life by providing isolations for frequencies as low as 10 Hertz and exhibiting low transmissibility at resonance (below 2.5) with .060" double amplitude vibratory input.

Applications

• Avionic equipment in propeller driven aircraft
• Sensitive instrumentation and medical equipment
• Stationary applications where cost effective, low frequency isolation is required

Benefits & Features

• 1-86lbs Per Mount Load Options
  • MS91418-1 size = .2-10lbs
  • MS91418-2 size = 2.0-43lbs
  • MS921418-3 size = 20-86lbs (Discontinued. No Longer available)
• Isolation performance maintained in attitudes up to 10º from the horizontal
• Low ratio of horizontal and vertical stiffness which holds transmissibility in rocking modes to unusually low magnitudes
