A cylindrical component that moves within a cylinder to transfer force from expanding gas in pneumatic actuators.
The piston is a precision-machined cylindrical component that reciprocates within the cylinder bore of a pneumatic actuator. It converts pneumatic energy into mechanical motion by responding to differential pressure across its surfaces. The piston forms a sliding seal with the cylinder wall via piston rings or seals, preventing gas leakage while allowing smooth linear movement. Its design includes features for rod attachment, seal grooves, and sometimes cushioning mechanisms to control end-of-stroke impact.

Piston wear results from friction against cylinder walls, contamination from particulates in compressed air, inadequate lubrication, misalignment causing uneven loading, and corrosion from moisture in air lines. Regular maintenance including air filtration, proper lubrication, and alignment checks minimizes wear.
Consider operating environment (corrosive, high-temperature), load requirements (static/dynamic forces), weight constraints, and compatibility with cylinder materials. Aluminum offers light weight, steel provides strength, stainless steel resists corrosion, and composite materials may be used for specialized applications.
Common failures include seal degradation leading to air leakage, scoring/galling of piston surface from contamination, fatigue cracking under cyclic loading, corrosion pitting in humid environments, and thread/stripping at rod connection points.
