In this video, we take a close look at the GUOMAT 1H4060 single convoluted flange air spring, a direct reference replacement for the Phoenix 1B04 rubber bellow. Watch a detailed walkthrough of its flange ring design, threaded hole layout, and key dimensions, followed by a demonstration of how it supports load, isolates vibration, and performs in industrial suspension and actuation setups. Ideal for engineers and buyers comparing replacement options.
