Rubber air springs are divided into three categories according to shape: capsule type, membrane type and sleeve type. According to the sealing structure, it is divided into four categories: pressure self-sealing type, rim clamping type, hoop sealing type and hybrid type.
This one is a bladder air spring. It can be used in many industrial equipment, such as presses, commercial washing machines, etc.
During transportation and storage, it should be kept as dry and cool as possible. At the same time, avoid exposure to the sun, prohibit contact with acids, alkalis, oils and other organic solvents, and keep away from heat sources.
