Precision-adjustable pneumatic cylinder featuring a unique external stroke adjustment ring mechanism for millimeter-level positioning accuracy. The hardened piston rod and double-seal design ensure leak-free operation even in high-cycle applications (up to 1,500,000 cycles). Includes magnetic piston for position sensing compatibility.

Typical Applications:

• Precision workpiece clamping in CNC machining centers
• Variable height positioning in automated assembly lines
• Die height adjustment in stamping/press machines
• Material handling systems requiring variable stroke control
• Packaging machinery with adjustable compression force

Installation tip: Always lock adjustment ring with included hex screw after setting stroke length. Use M3x0.5 thread sealant on sensor ports when installing magnetic switches. Lubricate through air port with ISO VG32 turbine oil during initial installation.

Note: When operating at maximum stroke (105mm), ensure cylinder extension clearance accounts for 120% of full stroke length. Not recommended for vertical downward load applications without external guides.
