Heavy-duty adjustable stroke cylinder with precision stroke adjustment mechanism. Features dual-side magnetic piston for position sensing compatibility and hardened anodized aluminum barrel for wear resistance. The enhanced buffer system reduces end-impact by 60% compared to standard models. Requires filtered air (40μm minimum) with dew point -25℃ below ambient.
- Press machine stroke control systems
- Automated material handling positioning
- Die casting equipment ejection mechanisms
- Plastic injection molding machine core pulls
- Automotive assembly line clamping fixtures
Installation note:
Adjust stroke by rotating the external locknut (torque ≤35N·m).
Maintain 20mm clearance from magnetic sensors.
Lubricate rod weekly in high-cycle applications (>500 strokes/min).
