This industrial-grade adjustable stroke cylinder features a unique dual-lock stroke adjustment mechanism that maintains position stability under 0.6MPa lateral loads. The chrome-plated piston rod incorporates a dust-resistant scraper ring, while the anodized aluminum body resists chemical corrosion in harsh environments. Requires filtered air with 5-40μm filtration and automatic lubrication systems (or regular manual lubrication every 500km stroke).
- Variable height positioning in automotive assembly jigs
- Pressure-sensitive clamping systems for CNC machining centers
- Adjustable ejector mechanisms in plastic injection molding
- Precision paper feed control in printing machinery
- Agricultural equipment with terrain-adaptive components
Maintenance tip:
Rotate adjustment screw clockwise in 1/4-turn increments for fine stroke reduction.
Always depressurize system before adjustments and lubricate guide shafts monthly
using ISO VG32 hydraulic oil.
