This situation may create the following risks: The rapid release of compressed air can generate a strong airflow, impacting surrounding equipment or personnel. If the pneumatic cylinder barrel material breaks upon rupture, fragments may be ejected from the cylinder structure.

When a cylinder exhibits symptoms such as air leakage, decreased thrust, unstable movement, or increased noise, it is likely necessary to inspect and replace the pneumatic cylinder kit.

A double-acting cylinder achieves the reciprocating motion of the piston by alternately inputting compressed air from both sides of the pneumatic cylinder barrel. It is precisely this characteristic of "bidirectional force and bidirectional motion" that places higher demands on the quality of the inner wall of a double-acting pneumatic cylinder barrel.

In some cases, certain parts of a pneumatic cylinder can indeed be repaired, such as replacing seals or making simple structural adjustments. However, when critical components (e.g., the cylinder barrel) are damaged, repairs often fail to restore original performance.

The pneumatic cylinder liner provides a stable trajectory for the piston. The piston reciprocates within the pneumatic cylinder liner, transmitting power to external devices via the piston rod. If the internal surface of the pneumatic cylinder liner is uneven or damaged, the stability of the piston's movement will be affected.

A sealing fit is formed between the pneumatic cylinder barrel and the seals. When scratches appear on the inner wall of the pneumatic cylinder barrel, the surface is no longer smooth, and the seals may not fit tightly when passing over the scratched area.
