3.4SMSR-AA/AF/AT - Spring Isolator/Restrainer

SMSR-AA/AF/AT spring mounts are designed to provide efficient isolation from critical vibrations and all-directional restraint from vertical and horizontal shocks, as well as from forces due to seismic activities and high wind loads.

There are three available configurations used during the installation of these spring vibration isolators:

SMSR-AA: top with an angle, and inside leveling adjustment feature
SMSR-AF: flat top, with inside leveling adjustment feature
SMSR-AT: bolted top with leveling adjustment feature

Recommended for vibration attenuation in:

HVAC equipment, fan air circulation systems, compressors, pumps, chillers, AC units, cooling towers, inertia bases, etc.
