Features

Superior Mechanical Design

Superior isolation effect in the VIB320X isolators is achieved by combined action of vertical spring and horizontal rollers. The balls are displaced between the parabolic shaped raceways due to micro-vibration and restored to the neutral position by gravity, acting akin to a pendulum. Horizontal deformation of the spring provides additional flexibility, thus leading to low natural frequency (as low as 3.25 Hz) and therefore excellent isolation of horizontal vibration. Isolation of vertical vibration is achieved by specially designed variable-pitch spring. When the load supported by isolators increases, the coils with smaller pitch settle on each other first, thereby reducing the effective number of active coils and increasing the stiffness of the spring. This way the stiffness of the spring increases by the same proportion as the supported mass, which leads to a constant natural frequency over the load range. This CNF (constant natural frequency) property leads to better overall isolation in multi-support spatial systems.

Wider Range Load Capacity

With improved mechanical spring design, the new generation VIB320X series isolators lowered its resonant frequency to provide more efficient vibration isolation at low frequency. The payload capacity range is almost doubled so it is more versatile for applications with changing load. The physical dimension stays the same which allows drop replacement for legacy VIB320 series isolators. Deflection_vs_Load, Resonate Frequency_vs_Load, and Transmissibility_vs_Frequency performance graphs of each model can be seen on individual product page.

Legacy VIB320 series isolators are still available. Click here for the complete list of legacy models.

VIB320X Isolators Featured in VIP Vibration Isolation Platform

Newport VIP320X general purpose and VIP3200 microscope platforms are compact, effective and easy-to-use platforms that significantly reduces vibrations from disturbing sensitive instruments such as microscopes, inspection or analysis equipment.

Patented Mechanical Isolation

VIB320X isolators are Newport's patented mechanical isolators using VIBe™ technology that are maintenance-free and user configurable. Featuring great robustness for tough environment, quicker settling time than pneumatic isolators and solid performance for vibration isolation, the VIB320X isolators are very popular among microscopy, precision measurement and inspection, and other sensitive applications.

Proper Loading

Each of the VIBe™ isolators in the platform needs to be properly loaded in order to achieve maximized vibration isolation performance. A special gap tool is shipped with the platform to verify the proper loading of the isolators. This gap tool measures 0.56 inch wide by 0.1 inch thick and it is used to determine that the gap in the isolator is more than 0.1 inch but less than 0.56 inch. If the gap is larger than 0.56 inch, the bearing does not have enough weight on it. Conversely, if the gap is smaller than 0.1 inch, it is overloaded.
