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.
