Silentflex® Tools
Vibration isolation calculator
Pick your application, enter the machine data and see instantly how much vibration you can stop, which natural frequency you need and which Silentflex® mounts fit.
Isolation chart
Where your machine sits
The classic selection chart: running speed across, natural frequency of the mounts down. Diagonals show the isolation you get. Your target is the dot; each Silentflex® family is a bar on your running speed. Tap one to plug it into the simulator.
Theoretical chart without damping, as in the standard selection method: fₙ = 15.8 / √δ.
Simulator
Plug in a mount and watch
Your machine, running on its mounts. Pick a Silentflex® family, plug it in and see how much vibration still reaches the floor. Slow motion, so you can see it.

For this family, an engineer will propose the exact model for your load.
Listen to it
What the floor below hears: your machine bolted down, then on the chosen mount.
Structure-borne noise
– dB(A)
Choose an application and plug in a mount to hear the difference.
Best with headphones.
Simulated with the same model as the calculator. Real installations usually reach 30–45 dB. It only cuts noise travelling through the structure, not airborne noise.

Other families (see why they do not fit)
Model: one mass on identical mounts, vertical only, damping typical for each construction. Each family covers several models; the simulation uses the softest one in the family. Indicative; an engineer confirms the final model.
