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.

The biggest problems in pneumatic system maintenance are compressed air quality and the condition of the system seals. These two issues directly affect the stability of the entire pneumatic system and ultimately manifest in the operating condition of the pneumatic cylinder barrel.

In conventional industrial applications, the movement speed of a pneumatic cylinder typically falls within the following range: 0.1 m/s ~ 1.5 m/s Under special design conditions, some pneumatic systems can even reach: Above 2 m/s

If the cylinder has a long stroke, even if the piston moves rapidly within the cylinder barrel, completing the entire stroke will still require a longer duration. Therefore, during the equipment design process, overall motion efficiency can be enhanced by optimizing the cylinder stroke.

Lubrication conditions have a significant impact on the service life of a pneumatic cylinder barrel. In pneumatic systems, the piston and seals undergo reciprocating motion against the inner wall of the cylinder barrel. If lubrication conditions are inadequate, frictional forces will increase significantly.

Unlike pneumatic cylinder barrels, hydraulic cylinder barrels need to withstand very high fluid pressures, therefore requiring higher strength and rigidity in their structural design. From a pressure-bearing capacity perspective, ordinary pneumatic cylinder barrels usually cannot meet the strength requirements of hydraulic systems.
