Vibro-Acoustics Free Spring with Top (FST) Series

Free Spring with Top


Vibro-Acoustics Free Spring with Top (FST) series provides vibration isolation for mechanical systems and equipment that are installed on floor or base. These unhoused isolators compress on neoprene cups and absorbing low and high frequency vibrations. FST isolators include a support plate for isolated components that cannot be secured with a bolted connection.

Springs are engineered to provide an additional 50% overload capacity. All other hardware is zinc plated including leveling and adjustment nuts.
