For air springs sealed with a hoop ring, the general inflation pressure should not be less than 0.07 MPa; for those utilizing flange clamping or self-sealing under pressure, the inflation pressure must be no less than 0.1 MPa. Typically, the design pressure of an air spring is one-third of its burst pressure; in optimal working environments, this design pressure can reach up to half of its burst capacity.
