    Polygonal Bellows

    The polygonal bellows are protections made from folded fabric and rigid PVC reinforcements in each fold. This type of bellows is used to protect linear guides, machine benches, racks, rods, spindles or different parts of a machine against dust, acids, oils, coolant, shavings, welding, abrasives, projections, high temperatures … Our system of manufacturing allows total adaptation to customer needs.
