High-precision adjustable stroke cylinder featuring a unique mechanical stopper system that enables ±2mm stroke fine-tuning. The triple-lip seal design ensures zero leakage at maximum pressure, while the dual-chamber cushioning mechanism reduces end-impact noise by 40% compared to standard models. Compatible with ATEX environments when used with proper filtration.

Installation guidelines:
Always degrease piston rod before first use. For stroke adjustment:
1) Loosen stopper lock nut
2) Rotate stopper screw (1 full rotation = 1.5mm stroke change)
3) Retighten with 2.5N·m torque
Maintain 0.5-1mm clearance between stopper and end cover during adjustment.
