The bellows for 3,500 kg axle load reliably protects the moving parts of your axle from dirt, moisture, and mechanical stress. It prevents dust and water from entering the bearing and damping areas, thus significantly contributing to the longevity and maintenance-free operation of the chassis. Made from high-quality, resistant rubber material, the bellows remains dimensionally stable and flexible even under heavy loads. Ideal for braked trailer axles with high payload – robust, precise fit, and low maintenance. An essential wear part for long-term operational safety.
