High-precision adjustable stroke cylinder featuring position-locking capability through its unique mechanical stopper system. The dual-cushion design minimizes impact noise while allowing fine adjustment of stroke endpoints (±2mm precision). Corrosion-resistant construction with integrated scraper ring prevents particulate ingress.
- Variable position clamping in CNC fixture systems
- Packaging line product height adjustment mechanisms
- Automated door stroke limitation in cleanrooms
- Plastic injection molding ejector systems
- Agricultural equipment with seasonal adjustments
 Installation recommendation: 
            Mount in horizontal orientation for optimal seal lubrication distribution. 
            Perform stroke adjustment with 0.2MPa test pressure before full operation. 
            Re-tighten stopper bolts after 50 cycles of initial use.
