About Berthold Marx

Berthold Marx SA is proud to have served the industry since 1945. Helping our customers solve their technical problems remains our goal. Since the early 70s, we have been developing both our knowledge in the gas spring market and an expertise on which our reputation is based.

Advantages of the gas springs over mechanical springs

  • A gas spring has a hydraulic damping length at the end of the stroke.
  • A gas spring is more compact than its mechanical counterpart.
  • A gas spring may reach a 20-year life span in certain applications, and still remain completely reliable.
  • A gas spring is easy to use.
