Air Spring vs. Steel Spring

The integrated sleeve air spring is a significant improvement on conventional steel spring structures, especially when it comes to driver comfort and safety. It is used in axle, cab and driver’s seat suspension systems. Our technology offers a significantly reduced natural frequency as well as individually adjustable stroke height and spring travel. Our solutions for specific applications are precision-engineered and extremely reliable.


  • High degree of ride comfort and reduced vehicle body wear and loading thanks to the low natural frequency
  • Constant natural frequency achieved by means of air pressure control and constant spring volume 
  • Constant vehicle height ensured by the level control system
  • Reduced road wear thanks to the low natural frequency
