1 NewDamp Constant Natural Frequency Elastomeric Isolators ND1 Series ND1- supports up to 2 lbs. and provides excellent CNF (constant natural frequency) characteristics: the vertical natural frequency is virtually constant at approximately 22 Hz for loads above 7 lbs. per isolator. This compact size isolator ensures excellent horizontal isolation with natural frequencies of to 7 Hz and minimum resonance amplification. The typical isolation characteristics are shown.

They provide almost equal isolation in vertical and horizontal directions. Within the same design envelope, they provide stiffer, higher load (ND3-); and softer, lower load (ND2-) options. By using custom profiled upper supports, these isolators can be easily tuned to particular load/frequency requirements. Model ND2-4. 4.

17 ND4 and ND41 Series These isolators are based on cylindrical elements. They are the best option for applications requiring good isolation and short settling time with respect to horizontal motions while maintaining low tilt due to moving loads.
