Heavy-duty adjustable stroke cylinder engineered for precision linear motion in industrial environments. Features a robust steel pipe structure with dual cushioning (internal rubber + external adjustable buffer) for smooth end-of-stroke deceleration. The through-rod design allows symmetrical force output and optional position sensing integration.
- Press machine ejection systems requiring variable stroke control
- Automated welding fixture positioning with shock absorption
- Foundry equipment handling high inertial loads
- Paper converting machinery with frequent stroke adjustments
- Automotive production line clamping devices
 Installation notes: 
            (1) Align cylinder axis within ±0.5° deviation to prevent side load.
            (2) Adjust buffer needle valve gradually (1/4 turn increments) for optimal damping.
            (3) Support cylinder mid-span when stroke exceeds 300mm in horizontal mounting.
