S-2000 Standard Version
The S-2000 vibration isolator incorporates many features of its highly successful predecessor the I-2000, including a patented self-centering pendulum design, laminar flow damping system and precision auto-leveling valves to deliver unmatched vibration isolation performance. Additionally, the new S-2000 design incorporates additional features and benefits including enhanced leveling indicators, recessed lifting channels and a significantly lower magnetic permeability design which greatly improves the ease of use, functionality and overall value for customers. The S-2000, with a 2000lb load capacity per isolator, is an ideal solution for isolating optical tables, large inspection equipment, heavy machinery and large area sub-floors. S-2000 isolators are availbale in standard, cleanroom and non-magnetic versions.
Exclusive laminar flow damping is the heart of the Stabilizers unparalleled performance. Unlike single damping orifices, the Stabilizer employs thousands of tiny orifices, resulting in greater damping efficiency overall. Combined with the hybrid chamber design to minimize air volume between piston motion and damper airflow, the Stabilizer protects applications like no other.Numerous performance advantages include:
Installation is fast and easy with patented, self-centering pistons. They automatically center the piston at the top and bottom of its vertical stroke, guaranteeing unrestricted movement for optimal performance. SafeLock mounting brackets eliminate the need to precisely align isolators and table holes when attaching the isolator to the table. Mechanical height adjustment allows quick and easy table leveling and compensates for non-level floors. Built in leveling indicators provide visual feedback ensuring the table is properly floating at the correct level.

The S-2000 series is available in three versions, the S-2000A, S-2000AC and S-2000AN. The S-2000A version is the standard isolator with leveling valves. The S-2000AC is a cleanroom isolator with leveling valves and the S-2000AN is a non-magnetic version with leveling valves constructed from aluminum and non-magnetic 316 stainless steel.We also offer other types of vibration isolators.

When you choose S-2000 Stabilizer vibration isolator, you have chosen not only the performance and quality of the product, but also our committed product support along your way. With over 40 years of experience in vibration control and isolation, Newport incorporates unparalleled wealth of knowledge and technology into the S-2000 Stabilizer vibration isolator to bring you the highest performance and most user friendly pneumatic vibration isolator soultion. Below are some of the features at a glance:
For pneumatic vibration isolators, lower natural frequency, higher damping efficiency and reduced diaphragm stiffness are desired to provide good isolation and damping. The natural frequency is related to the isolator compliance volume - the larger the volume, the lower the frequency. Damping efficiency is proportional to the air flow and pressure drop through the damper.
Conventional designs consist of a compliance chamber (the volume of which affects natural frequency), and a damping chamber. The two chambers are connected through a thin tube or a single orifice. Newport patented Stablizer hybrid chamber consists of a small size initial chamber and a second damping chamber together as a unified hybrid chamber, connecting them using laminar flow damping element. Because the initial chamber is reduced dramatically in size, it forces the isolator to use the second chamber as part of the compliance volume. The hybrid chamber thus offers much larger compliance volume for a given package size, and greatly lowers the natural frequency. Because the initial chamber is small there is a better linkage between piston motion and damping chamber air flow. This generates a higher damping force for a given piston displacement for faster, more efficient damping. S-2000 also uses custom molded ultra-soft diaphragms to reduce the stiffness to further improve the vertical isolation performance.
The pneumatic isolator offers isolation in the vertical direction; horizontal isolation is achieved through a mechanical filter system. Compared with other manufacturers' contacting bearing surfaces, Newport introduces zero friction trifilar pendulum system to eliminate the friction that commonly disturb high accuracy applications, thus enabling isolation to much lower vibration levels as well as high accuracy table repositioning after disturbances.
Self-Centering (US Patent 5071108) - Newport is the only company that offers self-centering for unrestricted piston motion, thus eliminating problems caused by shorting out the vibration isolator during table set-up.Height Adjustment - S-2000 Stabilizer includes an integrated, mechanical height adjustment system to allow improved table leveling, height control and compensation for non-level floors. Say goodbye to shims or spacers as those are not required to level a table sitting on S-2000 isolators.Modular Support Base - Need to change the isolator height for another application? No problem. S-2000 Stabilizer is built on modular support bases. Simply order new support bases to change your isolator to a new height.
Free-standing Design - S-2000 Stabilizer come standard without any mechanical connection between them. Freestanding legs are preferred for non-level floors and produce better decoupling from vibrations. We also offer Tie-bar systems as an option if the table will be moved frequently and requires a caster wheel system (order with -TC at the end).
SafeLock - S-2000 Stabilizer integrates exclusive SafeLock mounting clips, offering a safe and reliable connection of the isolator to the optical table. The brackets use a slotted connection to make installation easier. Numerous SafeLock secured systems have survived earthquakes throughout California and Japan. Earthquake restraints are available as a table accessory. Note: Optical table needs to be customized for Newport ERS earthquake restraints.
