Project Description

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

Barry L-Mounts increase equipment reliability and extend component-life by providing isolation for frequencies as low as 10 Hertz and exhibiting low transmissibility at resonance (below 2.5) with .60″ double amplitude vibratory input.

FEATURES

  • Marking of mounts with military designations available on special order
  • Aluminum construction
  • Axial to radial stiffness of 4:1
  • For base mounting only
  • Fail safe construction

BENEFITS

  • Isolation performance maintained in attitudes up to 10� from the horizontal
  • Low ratio of horizontal and vertical stiffness which holds transmissibility in rocking modes to unusually low magnitudes
  • Meets safety requirements of MIL-E-5400 (30G 11ms half sine pulse)

LOAD RANGE

  • L21/L22 = 7 load ranges from .35 – 4 lbs. per mount
  • L44 = 7 load ratings from .25 – 10 lbs. per mount
  • L64 = 7 load ratings from 2.0 – 40 lbs. per mount

APPLICATIONS

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

ENVIRONMENTAL DATA

  • Operating temperature ranges of -67°F to +250°F (-55°C to +120°C).
  • Meets vibration and shock requirements of MIL-C-172C.
  • L44 and L64 isolators are known as “MS” (Military Standard) mounts and appear on QPL’s.
