Spring bearings and elastomer bearings are typical products used to separate and isolate a vibrating system from a vibration source. They are placed between the source and the system, thus minimizing energy transfer from the source to the system. The natural frequency of the vibrating system f0, which is defined by the stiffness of the spring bearings or elastomer bearings and the supported mass, must be designed in such a way that it differs significantly from the excitation frequency of the vibration source fE .
