Note:

• The air spring can only move on the workpiece, or it must be equipped with a limit stop at the end of the stroke, otherwise the rubber material of the air spring will be overloaded or cause internal damage
• A reset force is required to compress the air spring to the minimum height. Usually achieved by applying external force
• The entire air spring surface of the upper and lower plates must be used to absorb force
• Before disassembling the air spring, the air pressure in it must be exhausted
•During operation, the wall of the air spring must not be in contact with other parts, otherwise the air spring will be worn and damaged and air leakage will occur.
