For applications with special requirements we also offer bellows made of Soft PVC, rubber disks or coated fabrics. Soft PVC bellows are resistant to oil, alkali and acid as well as water and dust. As molded parts for the economic production, a minimum quantity must be manufactured or an appropriate form must exist. Rubber disk bellows are of the highest quality and visually the most attractive protective covers for pistons and spindles. They are completely leak proof. Since each rubber disk lies flat on the other, excellent compression dimensions are achieved.
Rubber Fabric bellows are recommended for use if bellows are especially subject to heavy wear, high pressure conditions or high temperatures up to 200°C. Typical fields of application are piston rods with high ambient temperatures, or cardan shafts. Fabric bellows consist of a laminated structure with a special coating.
