Classic bellows, diverse forms that follow exceptional function

faltenbälge für den maschinenschutz

Our Classic series bellows have proven themselves more than a million times in a wide variety of applications. Arnold invented and patented bellows as a guiderail protector for use in mechanical engineering as early as 1930. Our bellows provide protection against cooling lubricants, dirt, dust, heat and greases. Classic bellows are made from an exceptionally wide range of available, high-performance materials – all tailored to our customers’ requirements.

Upon customer request, each protective bellow in the Classic line is individually tailored to your requirements. In addition to basic shapes like I and U bellows, roof bellows, box bellows and desk bellows, we also realize customer-specific geometries. Customers may also greatly benefit from our extensive experience and competencies in designing customized products for individualised mountings and guiderails.

Arnold bellows are literally "flexible”.

Design excerpt of Classic bellows:

  • Made out of technical fabric
  • Guiding frames provide shaping support
Connection of guiding frames with fabric by:
  • special welding process
  • sewing or stitching
  • gluing (laminating) several layers of material


  • Wide range of synthetic and natural technical fabrics with application specific high-performance coatings
  • Rigid support frames ensure high stability and long life-time
  • Large variety of bellow construction (sewing/ stitching, high-quality welding, laminating)
Advantages for our customers:
  • Highly flexible design, where almost all conceivable shapes can be realized
  • >100 qualified, resistant technical fabrics with appealing surface structure to choose from (incl. self-extinguishing, liquid-/ dust-proof)
  • Great “Made in Germany” manufacturing quality, including decades of bellow innovation

Basic shapes of bellows

Round bellows


Round bellows Rondet are used wherever mobility must be ensured, e.g. in spindles and joints. They provide reliable protection against heavy contamination in all materials offered.

Round bellows Rondet made of textile, rubber, PVC or fabric and leather have individual advantages and areas of application. These are detailed in the PDFs available for download.

Special bellows

Laser bellows/ beam guiding bellows:
For laser applications, we manufacture bellows made of special materials in terms of fabric, slider, structure and tightness.


Roof covers

Roof covers are suitable for protection against chips whirling out. These can be retrofitted to rear walls equipped for this purpose. Different possibilities of opening mechanisms make crane loading possible. For portal milling machines, the self-supporting roof covers for large widths of the Roover brand are suitable.

Bellows Lifting table Assembly lines

Lift table bellows - For lifting table bellows in assembly lines, we recommend e.g. an optical indication of the lifting position by the yellow edge protection in each fold. With these bellows, all options are open to you, even for very large dimensions. Thanks to our great material competence, it is also possible to manufacture the bellows in flame-retardant, self-extinguishing or flame-retardant versions.
