The SI40AX20S represents AirTAC's flagship compact cylinder with precision-machined guide bearings, optimized for high-cycle automation systems. Its dual-layer chromium plating on the piston rod provides 2x standard wear resistance compared to basic models. The cylinder features an integrated anti-rotation slot (3mm width) for stable linear motion in pick-and-place applications.
