Technical insights
Practical guides on vibration isolation, written by our engineers.
How to choose an anti-vibration mount: load, natural frequency and isolation
A five-step method to select vibration isolators: load per mount, excitation frequency, required natural frequency, environment and mounting direction. With worked examples.
Metal wire mesh or rubber mounts? How to choose for harsh environments
Stainless steel wire mesh and rubber anti-vibration mounts compared: temperature range, damping, ageing, fatigue and when each one is the right choice.
Seismic protection for data centres: what GR-63-CORE Zone 4 means
What the Telcordia GR-63-CORE Zone 4 seismic test involves, why TIA-942 refers to it, and how a container with live IT racks passed it on Silentflex® Container Pads.
