Even small cracks can propagate rapidly under air pressure, leading to cylinder barrel rupture. Furthermore, a cracked pneumatic cylinder barrel can cause gas leakage, affecting the normal operation of the cylinder. Therefore, from a safety and reliability perspective, continuing to use a cracked pneumatic cylinder barrel poses a significant risk.

Untreated aluminum alloys have low hardness, while the oxide film formed after anodizing can achieve a hardness of: • HV200 ~ HV500 (or even higher) This means that the pneumatic cylinder barrel is less prone to wear during long-term operation.

Since the piston area is directly determined by the inner diameter of the pneumatic cylinder barrel, it follows that a larger bore diameter results in a larger piston area; consequently, under identical air pressure conditions, the cylinder is capable of generating a greater thrust force.

If the machining precision of the pneumatic cylinder tube is insufficient, it may lead to: •Gas leakage •Unstable piston movement •Damage to the seals •A decline in cylinder efficiency Therefore, from a functional standpoint, high-precision machining is a fundamental requirement for the pneumatic cylinder tube, rather than merely an optional add-on.

For the majority of pneumatic cylinder barrels, given that their wall thickness is relatively small compared to their inner diameter, they can typically be analyzed and calculated using the principles applicable to thin-walled cylinders. The fundamental formula is: σ = (P × D) / (2 × t)

In principle, a pneumatic cylinder barrel relies on compressed air to drive piston movement; its fundamental operating mechanism does not change simply because the temperature drops. Therefore, within a certain range, a pneumatic cylinder barrel can still function normally.
