Precision-engineered adjustable stroke cylinder featuring dual-position mechanical stoppers with ±1mm repeatability. The hardened piston rod (HRC 35-40) and anti-rotation guide design ensure stable linear motion in high-side-load applications. Integrated magnet slots (T-slot on rod) support position feedback sensor installation.
- Variable height positioning in automated assembly lines
- Pressure-sensitive clamping systems (PCB manufacturing)
- Packaging machinery with product size variation
- Glass handling equipment requiring soft-stop cushioning
- Automated welding jigs with adjustable reach
 Installation tip: 
            Use M6 mounting bolts (8.8 grade min.) with 0.05-0.1mm clearance. 
            For vertical installations exceeding 45° angle, install an external guide mechanism. 
            Lubricate rod weekly with ISO VG32 hydraulic oil in high-cycle applications.

         Critical note: 
            Do not exceed 1.2MPa peak pressure. Adjust cushion screws incrementally 
            (max 1/4 turn per adjustment) while monitoring deceleration.
