ND01 Series
ND01-A NewDamp elastomere isolator
The ND01-A supports up to 250 lbs. and provides excellent CNF (constant natural frequency) characteristics: the vertical natural frequency is virtually constant at approximately 22 Hz for loads above 70 lbs. per isolator. This compact size isolator ensures excellent horizontal isolation with natural frequencies of 5 to 7 Hz and minimum resonance amplification. The typical isolation characteristics are shown.
NewDamp™ ND20 and ND30 Series
Customized ND20 NewDamp™ Elastomeric Isolator.
ND30-A NewDamp™ Elastomeric Isolator.
These isolators are based on conical elastic elements. They provide almost equal isolation in vertical and horizontal directions. Within the same design envelope, they provide stiffer, higher load (ND30-A); and softer, lower load (ND20-A) options. By using custom profiled upper supports, these isolators can be easily tuned to particular load/frequency requirements.
ND40 and ND41 Series
Customized ND41 NewDamp™ Elastomeric Isolator.
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.
These isolators are based on conical elastic elements designed for low load applications. The ND50 supports loads up to 40 lbs.
ND Settling Time vs. Other Isolators
A remarkable property of NewDamp™ isolators is their ability to quickly attenuate the transient motions, thereby reducing the settling time of the equipment after the stage movements or other disturbances. The following comparison was made for a dual-axis air bearing stage mounted on a granite basis (total weight: 800 kg) and supported by four NewDamp™ ND40 isolators.
Custom machinery feet offer high horizontal damping with vertical stiffness.
