Kastenbälge

Rectangular Box Bellows

Dynatect’s box bellows are designed to protect machinery and equipment from dust, oils, and heat, as well as incidental contact in dynamic machine environments. Featuring a dimensionally stable design (retains its shape during operation) and fold-resistant construction, these bellows are customized to customer requirements in both shape and size. Depending on their dimensions, they are either heat-sealed or sewn. Both manufacturing methods deliver a precise and reliable protective solution. Typical applications include lift tables, medical equipment, and automation systems.
