Are there other points to consider to be assured of obtaining the isolation desired? |

There are other points to consider, such as:
The isolator support must be rigid compared to the isolator. A general rule of thumb is to have the support spring rate 10 times that of the isolator spring rate, which means that the isolator natural frequency is no more than one-third that of the lowest support frequency.
When isolating a unit with a high center of gravity, the isolators should be located on centerlines that are at least twice the radius of gyration. This will assure good stability.
All line connections to the isolated unit should be isolated. If they are not, then flexible connections must be used. This will avoid "short-circuiting" of the isolation system.
If there is excessive movement of the equipment on its isolators, then an inertia mass must be incorporated. A reinforced concrete block is generally used, but steel could be used if space were a problem since it is heavier than concrete. This added weight is placed directly beneath the machine and supported by the isolators. It provides resistance to motion as well as the following additional benefits:
- Maintains alignment between driver and driven.
- Adds rigidity to the machine base.
- Lowers the "center-of-gravity".
- Increases centers between isolators for added stability.
