Metal Bellows Dampers

Taylor Devices has created a damper that has absolute zero leakage due to hermetically sealed construction making it ideal for both structural and space applications. 

Metal Bellows Dampers Provide Unique Damping Solutions

Metal bellows dampers were developed during the 1980’s for NASA and used on platforms based in outer space. Conventional sliding surfaces that were sealed acceptably on earth proved unacceptable for spacecraft use.

Taylor Devices Damper Sleeve

Metal bellows dampers are unique hermetically sealed dampers that were originally developed for use on platforms that were critical during space missions. The reason was simply that even the tiniest amount fluid leakage past conventional seal turns into a dense fog in a vacuum, contaminating optics and electronic systems.

Applications of Metal Bellows Dampers


Today, these same dampers have been successfully adapted for use in structures for protection against wind and seismic events. Additionally, metal bellows dampers are ideal for applications requiring damping at very low displacements, including human-induced vibration for bridges and buildings.


Metal bellows dampers continue to be ideal for space applications because of the fact that even the tiniest amount of fluid leakage past conventional seals turns into a dense fog in a vacuum. Our metal bellows dampers provide absolute zero leakage, infinite life, and no maintenance.

The Case of the Millennium Bridge

The Millennium Bridge or “Wobbly Bridge” is an interesting story on how human induced motion caused the bridge to sway causing unsafe conditions for pedestrians. The bridge opened to the public on June 10, 2000 and measures 320 meters long and crosses the River Thames. On opening day, pedestrians walked across the bridge and, to their surprise, it began to sway. While some bridge sway is normal, the swaying got larger and larger until it was deemed unsafe. Luckily there were no serious injuries, but the bridge was immediately closed.

Although the bridge was designed to withstand wind and weight, the engineering design did not factor in human behavior.

Metal Bellows Dampers in Buildings

Metal bellows dampers can be used in tall buildings that experience continuous swaying due to wind activity. Unlike dampers that are used for seismic activity, metal bellows dampers can provide damping at very small displacements, have near-frictionless performance, and can withstand the nearly constant cycling, from high winds. One example application of this incredible product is located at the top of the 250 West 55th Street building in Manhattan.

Another example of our metal bellow dampers in building applications is located in mega-bracing in the 181 Freemont building in San Francisco, CA.  Similar to the building in Manhattan, our dampers not only needed to reduce wind oscillations but also absorb vibrations from major seismic activity. Instead of stiffening the building, the building’s engineering team decided on the opposite approach, which was to reduce stiffness to allow flexibility, and then add dampers to reduce the seismic demands.

Benefits of Metal Bellows Dampers

  • Infinite Life – The only damper design in the world that is designed for infinite life. Parts are stressed below the material fatigue endurance limit ensuring that the dampers will survive billions of cycles.
  • Virtually Zero Friction – There is no source of friction typical of standard elastomeric seals.
  • Effective damping at extremely small amplitudes.
  • Extremely High Fidelity response to shock and vibration over a frequency band of 0-500 Hz and amplitudes as low as +/- 0.001 inches (+/- 0.00254mm) or less. 
  • High series stiffness for high damping effectiveness
  • Various damping functions are achieved based on a customer requirement
  • Taylor metal bellows dampers are designed and tested in output force ratings up to 450 KIP or more and strokes up to +/- 20 inches or more. 
  • No Maintenance over the life of the structure or dynamic system.
  • Absolutely ZERO Leakage due to hermetically sealed construction.

The following update is from company president, Alan Klembczyk.

March 20, 2020

To the Customers of Taylor Devices:

Due to the ongoing dynamics of the situation with respect to the Coronavirus, I feel that it is necessary to update our customers yet again. As of today, there has been a significant development for us, so I want to convey our current status.

The Governor of New York State, Andrew Cuomo, today updated his Executive Order mandating that 100% of their workforce stay home, with certain exceptions.

Before explaining how that impacts us, please allow me to clearly state that we continue to monitor and adhere to the advice of the appropriate public health agencies. Our Executive Management team is in continuous communication with each other and we are reacting accordingly to minimize any possible impacts that this situation may cause in satisfying all our customer’s needs.

We continue to follow the Center for Disease Control (CDC), Occupational Health and Safety Administration (OSHA) and the Niagara County Health Department for news and advice on steps that should be followed. We are following the recommendations of those agencies.

Because Taylor Devices provides products and services for defense and national security-related operations supporting the U.S. Government and is a contractor to the US government, we are continuing our operations on a limited basis to support our requirements. This allows us to maintain at least a minimal workforce, including some office staff and some personnel who are supporting manufacturing, assembly, and testing operations.

We have taken substantial measures to allow certain other employees to work from home if their job function allows. Therefore, we are fortunate to be in a position that allows us to maintain many functional aspects of our Company while still practicing cautious measures to inhibit the spread of the Coronavirus.

Please continue to be assured of the following points:

  • TDI Management has taken substantial measures to maintain our ability to meet our obligations to our customers while adhering to the recommendations and regulations of government agencies. Our workforce remains confident, high- spirited and healthy. We have a sufficient workforce that have adjusted their work schedules as necessary. We remain confident that we will continue to meet the ongoing challenges that the situation is presenting to us.
  • Our Purchasing team is in continuous communication with our suppliers so that we can be updated on any delays that may occur. To date, there still have been no delays in receiving our raw materials, purchased components or outside services that affect our final product.

  • We are managing this crisis with plans and protocols, which includes the ability for many of our employees to work remotely and seamlessly to support our customers while keeping our employees safe.

  • Our cleaning service at our factory has stepped up cleaning and disinfecting, especially in high-use areas such as bathrooms and lunchrooms.

  • We have eliminated non-essential travel.

  • We have put into place a policy of reporting any personal travel by staff or family members outside of Western New York to Human Resources to determine if any quarantine measures will need to be taken, especially if the travel is to high-risk exposure areas or on cruise ships.

  • We have added a formal visitor pre-screening process that we now require all visitors that enter our facilities to complete.

Please be assured that Taylor Devices continues to hold a very high standard for all our customers while ensuring the safety of all our employees and our professional associates. Our Sales Staff is always available to answer any questions that you may have, and we will continue to support our customers to the absolute best of our abilities.

Thank you very much for your confidence in us to manage this challenging situation.
