Anti-Seismic Preloaded 4V-SX Spring Mounts
Preloaded anti-seismic spring mounts with static deflection up to 76 mm (3 inches), providing a natural frequency of approximately 2 Hz.
AMC-MECANOCAUCHO® Anti-Seismic Preloaded 4V-SX Spring Mounts are designed for applications requiring high-performance low-frequency vibration isolation, combined with mechanical protection under seismic conditions.
With a static deflection of up to 76 mm (3 inches), the springs provide a natural frequency of approximately 2 Hz, ensuring a very high level of low-frequency vibration isolation.
The adjustable preload system facilitates installation by maintaining the spring mount at a predetermined height before the equipment load is fully applied. This design helps prevent sudden settlement of the equipment during installation and facilitates system levelling.
A Sylomer® layer helps reduce the transmission of medium- and high-frequency vibrations that may propagate through the steel springs. The spring + Sylomer® combination therefore provides effective vibration isolation over a very wide frequency range.
The integrated seismic restraint system limits excessive equipment movement under exceptional loads, while allowing the movement required for effective vibration isolation under normal operating conditions.
Technical characteristics
This range of supports consists of:
A spring with high elasticity and very low natural frequency.
An incorporated levelling system.
An incorporated preload system.
A Sylomer® pad under the mount base in order to isolate mid-high frequencies.
