MS91527 Series

MS91527 Series Vibration Isolators are Defined by the MS Specification as:  Mounts, Vibration, Cup-type, Classes A & B, For Use With Electronic Equipment In Aircraft.

Low-frequency, highly damped mounts for a high level of vibration isolation. Hutchinson MS91527 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

• 0,2-86lbs Per Mount Load Options
