An air spring device comprising:
- an air spring bellows which is made from elastomeric material and is clamped in an airtight manner between an air spring cover and an air spring rolling piston, the air spring bellows rolling on the air spring piston upon forming a rolling fold and being fastened to the air spring cover upon forming a second fold, and
- an outer guide which encloses the air spring bellows in a sleeve-shaped manner and a folding bellows which protects the rolling fold against contaminants,
- wherein the folding bellows is fastened to an end of the rolling piston which lies opposite the rolling fold,
- the outer guide has one end located proximal to the rolling piston and another end located distal from the rolling piston,
- the folding bellows is fastened to the distal end of the outer guide, and
- the folding bellows includes a portion extending away from the rolling piston beyond the distal end of the outer guide.
