Rubber bellows are flexible protective components designed to shield moving mechanical parts from dust, water, oil, and external contaminants. Thanks to their high flexibility and durable construction, they provide long service life in machinery systems, hydraulic applications, the automotive industry, and various industrial equipment. Formül Kauçuk manufactures rubber bellows in different sizes and custom designs according to customer requirements.
Bellows can be produced from EPDM, NBR, Neoprene (CR), Silicone, and other elastomer materials depending on application requirements. Custom manufacturing based on technical drawings or samples is also available.
