Polybond COMBIMOUNTS consist of two PS type sandwich mounts housed together in specially designed iron castings for protection against oil and mechanical damage. These are special mountings with natural frequencies down to 5.5 hz and very goood lateral stability. For low disturbing frequencies, high deflection can be achieved by screwing two combimounts ps together along with the flange. When they cannot be bolted, these mounts can be located by rubber friction pads.
