High-precision adjustable stroke cylinder featuring dual-position locking mechanism for mid-stroke positioning. The integrated shock absorber minimizes end-impact noise (≤65 dB) while maintaining 95% energy absorption efficiency. Corrosion-resistant construction with IP54 rating makes it suitable for humid environments.
- Precision workpiece positioning in CNC tool changers
- Variable height adjustment in packaging sealing machines
- Material clamping with pressure-sensitive components
- Automated paint spray systems requiring stroke flexibility
- Semiconductor handling equipment with space constraints
 Installation note: 
            Lubricate with ISO VG32 hydraulic oil before initial operation. 
            Maintain 0.3–0.6 MPa pressure during adjustment screw calibration. 
            Allow 20mm clearance behind stroke adjustment mechanism for maintenance access.
