Introduction of F-type self-sealing air spring (for punching equipment):

Self-sealing is named for its self-sealing without external force. As shown in the figure, the rubber curved bladder:

① which is reinforced with a fiber layer is embedded with a steel (galvanized) waist ring

② that prevents expansion when in use.

③The traveler at the end of the cover plate is Under the action of pressure, the rubber mouth is deformed and in close contact with the upper and lower cover plates (galvanized)

④, thereby preventing air leakage. The upper and lower cover plates are formed by machining.

⑤ is the pipe thread intake hole for installing the intake pipe, and

⑥ is the installation  standard threaded holes used.

Punch air springs are different from other types of air springs.
The punch air spring is more complex and strict in the manufacturing process; the force of the punch air spring is also different, so the bag of the punch air spring is thicker and resistant to impact.
