Bellows

Folding bellows, corrugated bellows and fairings – flexible connecting elements for all applications.

 

We produced our first folding bellows in 1952. At that time, together with the Henschel Company in Kassel, we brought their first articulated bus to the market. In 1956, the first folding bellows for rail vehicles came on the market when we equipped the TEE high-speed train with folding bellows, and in 1971 we delivered our first folding bellows for airport technology. Over the years, we have been continually developing our folding bellows so that today they are put to use in all kinds of different applications– for example as flexible connecting elements between skyscraper towers or as noise protection equipment during drilling operations. And we have also extended and enhanced the look of our folding bellows. Nowadays, translucent or multicolored folding bellows can be seen in use in many places.

 

Folding bellows, corrugated bellows and aerodynamic wind fairing systems

Folding bellows are exceedingly light and economical. They are used particularly often in buses, trams, monorails and in technical building applications.

Corrugated bellows have better sound insulation and heat insulation characteristics than folding bellows. Double-corrugated bellows have the same basic characteristics as single-corrugated bellows but insulate more effectively. They are also more stable and less permeable under pressure.

HÜBNER also produces aerodynamic wind fairing systems. These are available in a complete integrated bellows model or in a rubber version. With their aerodynamic characteristics they can result in energy savings of up to 10%.
