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.

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.

Generally, the radial clearance between the pneumatic cylinder barrel and the piston is typically in the range of 0.01mm to 0.05mm (depending on size grade), but the specific value must be determined in conjunction with design standards and operating conditions.

When purchasing pneumatic cylinder barrels, the following methods can be used to assess product quality: • Choose a manufacturer with mature production processes • Inspect the pneumatic cylinder barrel machining and testing equipment • Understand the quality control standards in the production process

From an engineering maintenance and mechanical structure safety perspective, although some minor problems can theoretically be repaired by machining, in most cases, a deformed pneumatic cylinder barrel is better suited for direct replacement than repair.

Common internal wall treatments in pneumatic cylinder barrel manufacturing include: • Boring • Honing • Grinding • Polishing • Surface coating These processes are typically not used individually, but rather in combination based on the design requirements of the pneumatic cylinder barrel.
